San Antonio Police Headquarters Hit By Gunfire: VIDEO

San Antonio, TX -- The police headquarters was fired upon Saturday night, the San Antonio police chief said.

The shooting occurred just before 10 p.m. on Saturday, and investigators found the impact craters on the upper building of the police headquarters building downtown. San Antonio Police Chief William McManus said several shell casings were found in an adjacent alley.

McManus said no injuries were reported, despite the presence of several detectives inside the building at the time the shooting.

A man seen running from the scene was briefly detained, but it was later determined he was not a suspect. Police did release a description of the suspect, describing him as a Hispanic man.

Police deployed a bomb squad to check out a vacant car near the building originally suspected of being tied to the shooting in an abundance of caution, the chief said. The also cordoned off a large area fronting the headquarters building, located at 315 South Santa Rosa.

The shooting comes three days after an ambush-style attack of police officers guarding a rally among civil rights advocates that claimed the lives of five law enforcement officers.

McManus noted the building has been shot at before, but believes this time it was done by someone who may have been inspired by the Dallas shooting or a growingl backlash against law enforcement.

"It's alarming," McManus said. "It's not the fist time our building has been shot at, but it's too coincidental that it's around the time that officers are being threatened in cities across the country, especially here in Texas."

McManus staged a press briefing outside police headquarters updating reporters on the investigation:
