SAN ANTONIO -- Members of the San Antonio Police Department's bomb squad detonated a suspicious package shortly before 11 a.m. after a building and surrounding streets were shut down.

Investigators were able to determine that there were no explosives inside.

Emergency crews were called to the San Antonio Public Safety Headquarters, located at 315 S. Santa Rosa Ave., at 10 a.m. after an internal affairs officer spotted a black bag from his window.

The exact contents of the bag were not immediately available, however, there were a few miscellaneous items, including paper and a plastic bag inside, said SAPD spokesman officer Douglas Green.

Investigators will work to determine who left the bag and whether there was any intent to cause harm.
