Whoa.

The day Ahmad Khan Rahami allegedly planted two bombs in Chelsea — one of which detonated on West 23rd Street — two thieves accidentally helped to disable his second pressure cooker bomb left inside a rolling suitcase on West 27th Street, sources said.

The young men, who sources described as being well-dressed, opened the bag and took the bomb out, sources said, before placing the explosive into a garbage bag and walking away with the rolling suitcase.

In doing so, investigators believe they inadvertently disabled the explosive, sources said. That allowed investigators to examine the cellphone attached to the bomb intact and discover that it was connected to the family of Rahami.

This report also claims police “found a website where Rahami allegedly posted jihadist missives” on the phone left with the bomb.

He’s a victim. Via Daily Mail:

The prime suspect in the New York and New Jersey bombings sued his local police force and claimed they were persecuting him for being a Muslim.

Ahmad, 28, his father Mohammad Sr, 53, and his brother Mohammad, brought the lawsuit together and said that local residents also racially abused them and said: ‘Muslims don’t belong here’.

The lawsuit was filed in 2011 and reveals that Ahmad has a long history of grievances with city officials, their local police force and people who lived close to them.

Odd biographical detail via NYTimes:

Ahmad Khan Rahami, the man wanted in the bombing, is the son of a man named Muhammad Rahami who runs a fast-food restaurant, First American Fried Chicken, in the ground floor of their home on Elmora Avenue, neighbors said.

The restaurant, which has employed Ahmad and some of his brothers, was such a persistent neighborhood nuisance that the city forced it to close early, said Mayor J. Christian Bollwage of Elizabeth.

When it was opened several years ago, it stayed open all night, Mr. Bollwage said.

Neighbors, including Dean McDermott, who lives on the corner of Linden and Elmora Avenues and works as a news videographer, said the restaurant drew rowdy crowds past midnight.

NEW YORK (AP) — Agents with the FBI pulled over a car on a highway in Brooklyn on Sunday night and were questioning the vehicle’s occupants in connection with the investigation into the New York City bombing that injured 29 people, authorities said.

Agents stopped “a vehicle of interest in the investigation” at 8:45 p.m. Sunday, according to FBI spokeswoman Kelly Langmesser

She wouldn’t provide further details, but a government official and a law enforcement official who were briefed on the investigation said five people in the car were being questioned at an FBI building in lower Manhattan.

The officials spoke on condition of anonymity because they were not authorized to speak about the ongoing investigation.

No one has been charged with any crime and the investigation is continuing, Langmesser said.

‘I walked 10 or 15 feet on the block and I saw a strange contraption – a pot with wires coming out of it,’ Schreibman told the DailyMail.com.

‘My first thought was it was a kids’ science experiment that they were throwing out.’

Schreibman continued walking but the road was closed, forcing her to turn back. She thought she should take another look.

The pot, she said, had wires coming out of it and had been left near a mailbox. It had duct tape around the lid, to hold the lid down and to keep the wires in place.

From the Associated Press — Gov. Andrew Cuomo insists there is no tie to international terrorist organizations.

NEW YORK (AP) — Gov. Andrew Cuomo said Sunday a blast that injured 29 people in Manhattan was caused by some kind of bomb, but the attack didn’t appear to be linked to international terrorism.

Cuomo, speaking near the scene of the Saturday night blast, told reporters a second device found blocks away from the first explosion appeared “similar in design” to the first, though investigators are still testing its remnants after it was removed by a bomb squad robot and blown up at a police facility in the Bronx.

The bombing rocked the city’s Chelsea neighborhood, a mostly residential part of Manhattan’s west side known for its art galleries and large gay population. Witnesses described hearing a deafening blast, and surveillance video footage captured images of nearby windows being blown out by the explosion as people sprinted away from the scene.

“We will find whoever planted these explosives and they will be punished,” said Cuomo, a Democrat. He said all 29 people who were injured have been treated and released from a hospital.

NEW YORK (AP) — An explosion rocked a crowded Manhattan neighborhood and injured 29 people, and a suspicious device discovered blocks away was safely removed early Sunday. Mayor Bill de Blasio ruled out any terror connections but called the blast an “intentional act.”

“Tonight, New York City experienced a very bad incident,” de Blasio said at a news conference near the scene in Chelsea. “We have no credible and specific threat at this moment.”

De Blasio tried to calm any fears among nervous New Yorkers, saying the explosion had no terrorist connection and wasn’t related to a pipe bomb explosion earlier Saturday in New Jersey that forced the cancellation of a charity run.

“Now, I want to be clear: Whatever the cause, whatever the intention here, New Yorkers will not be intimidated,” the mayor said. “We are not going to let anyone change who we are or how we go about our lives.”

It was unclear who was behind the blast and what motivated it.

A law enforcement official told The Associated Press that a second device that officers investigated four blocks from the scene appeared to be a pressure cooker attached to wiring and a cellphone. The official, who was not authorized to speak about an ongoing investigation and spoke on condition of anonymity, said the device was found inside a plastic bag on West 27th Street. The device was removed with a robot and taken to a department firing range in the Bronx.

The law enforcement official also said that the explosion that rocked a bustling Chelsea neighborhood appeared to have come from a construction toolbox in front of a building. Photos from the scene show a twisted and crumpled black metal box.

The blast happened on West 23rd Street, in front of a residence for the blind, near a major thoroughfare with many restaurants and a Trader Joe’s supermarket. Witnesses said the explosion at about 8:30 p.m. blew out the windows of businesses and scattered debris in the area. Officials said no evacuations were necessary.

The Fire Department of New York said 24 people were taken to hospitals with injuries. One person received a puncture wound that was considered serious. The other injuries were described as scrapes and bruises.

New York City subway routes were affected by the explosion, which rattled some New Yorkers and visitors on the heels of the 15th anniversary of the 9/11 terror attacks.

Chris Gonzalez, visiting from Dallas, was having dinner with friends at a restaurant in the area.

“We felt it. We heard it,” Gonzalez said. “It wasn’t like jolting or anything. Everyone just went quiet.”

Rudy Alcide, a bouncer at Vanity Nightclub at 21st Street and 6th Avenue, said he, at first, thought something large had fallen.

“It was an extremely loud noise. Everything was shaking, the windows were shaking,” he said. “It was extremely loud, almost like thunder but louder.”

The FBI and Homeland Security officials, along with the Bureau of Alcohol, Tobacco, Firearms and Explosives arson and explosive task force, were at the scene.

The White House said President Barack Obama was apprised of the explosion.

In St. Cloud, Minnesota, police said at least eight people were injured at a shopping mall Saturday evening in a stabbing attack. The suspect was shot dead by an off-duty police officer.

Democratic presidential nominee Hillary Clinton said she had been briefed “about the bombings in New York and New Jersey and the attack in Minnesota.”

She says the nation needs to support its first responders and “pray for the victims.”

“We have to let this investigation unfold,” she said.

Donald Trump moved ahead of New York City officials when he declared a “bomb went off” before officials had released details. He made the announcement minutes after stepping off his plane in Colorado Springs, Colorado.

“I must tell you that just before I got off the plane a bomb went off in New York and nobody knows what’s going on,” Trump said.

He continued, “But boy we are living in a time – we better get very tough, folks. We better get very, very tough. It’s a terrible thing that’s going on in our world, in our country and we are going to get tough and smart and vigilant.”

The Republican presidential nominee made the comments around 9:10 p.m., shortly after the explosion and as emergency officials responded to the blast. A spokeswoman for Trump did not respond to an email asking whether he was briefed about it before taking the stage.

The Manhattan blast came hours after a pipe bomb exploded in Seaside Park, New Jersey, shortly before thousands of runners were due to participate in a charity 5K race to benefit Marines and sailors. The run was canceled, and no injuries were reported.
