DALLAS (CBSNewYork/AP)– At least two Dallas Police Department buildings were blocked off Saturday evening, with numerous police vehicles and armed officers outside.
Officers in helmets carrying rifles were outside the buildings Saturday evening. Police also are standing outside a building behind police headquarters.
It wasn’t immediately clear what police are investigating. Maj. Thomas Castro says several general threats have been made against Dallas police, though nothing specific.
Dallas police said they searched for a suspicious person in a parking garage next to its headquarters, but that no suspect was found, CBS2’s Kenneth Craig reported.
A Dallas police spokeswoman said earlier Saturday that the department received an anonymous threat against law enforcement across the city and has tightened security.
Police also have shut down a street in front of the department’s headquarters amid the heightened police presence.
