ORIGINAL REPORT:

WFAA is reporting that the Dallas police headquarters building is in lockdown and a SWAT team has been deployed after a threat was received. In a prepared statement Saturday evening, the Dallas PD said, “The Dallas Police Department received an anonymous threat against law enforcement across the city and has taken precautionary measures to heightened security.”

Dallas police are saying they received a credible threat that a group from Houston is claiming to be armed and headed to Dallas with the intent to kill more police officers, according to KTRK ABC13 in Houston.

WFAA has reporters on the scene who are saying multiple SWAT vehicles and personnel are on the scene.

Reporters from Dallas said officers told them shots had been fired and an ambulance was seen on-site.
