(CNN) — The bomb squad is canvassing the area around where a gunman targeted three buildings — including police headquarters — early Friday in downtown Austin, Texas, before a police officer shot and killed him.
Authorities started receiving 911 calls around 2:25 a.m. (3:25 ET) Friday about gunfire in in the Texas capital, Assistant Chief Raul Munguia told reporters.
An Austin police officer outside headquarters saw the suspect and shot him, Munguia said.
The officer noticed what appeared to be an improvised explosive device in a vehicle near the fallen gunman, who was pulled away across the street.
Officers ended up backing away from the suspect after noticing he “was wearing some type of vest,” Munguia said.
Authorities didn’t indicate that there were any additional shooters, and no one besides the suspect was shot.
The shooting prompted the evacuation of police headquarters, which is near the Mexican Consulate.
Video from CNN affiliates KXAN and KEYE showed the flashing lights of a large number of police cars and at least one ambulance lighting up the early morning sky in downtown Austin.
Officers blocked traffic in several areas, and police retweeted a warning that drivers should expect delays and detours in a multiblock downtown area from Interstate 35 to the east.
