Six people have been arrested in New York for threatening NYPD officers since officers Rafael Ramos and Wenjian Liu were executed last weekend.

According to a Reuters report, two more men were arrested on Wednesday for making terroristic threats:

Tyrone Melville, 41, of Manhattan, was arrested on Wednesday after he allegedly called the switchboard of Brooklyn’s 84th Precinct, where the slain officers were based, said Sergeant Carlos Nieves, a police spokesman.

Requesting to speak to Ramos, Melville asked if the bullets had been removed from the dead officer’s head so “he could kill more cops,” Nieves said.

Melville was charged with making terroristic threats, a felony, and aggravated harassment, a misdemeanor.

Jose Maldonado, 26, was charged with making terroristic threats after allegedly threatening on his Facebook page to kill police officers and posting pictures of weapons, Nieves said. Maldonado also was arrested on Wednesday.

Four others “have been charged with making terroristic threats or making false 911 calls” while the NYPD has reportedly “received more than 40 threats” since Ramos and Liu were murdered. In addition, at least two NYPD precincts have received bomb threats.

Last weekend, Liu and Ramos were executed in cold blood in retaliation for Eric Garner’s death. In the weeks leading up to their murders, New York City Mayor Bill de Blasio (D) and agitators like Al Sharpton fanned anti-police sentiment, not even denouncing demonstrators who shouted, “What do we want? Dead cops! When do we want it? Now!”
