The FBI and Homeland Security are investigating after shots were fired at two ICE offices housed at a building in San Antonio early Tuesday morning.
Bullets pierced a window of an ICE office and Removal Operations Field Office inside the Jefferson Bank building about 3 a.m., KENS-5, a CBS affiliate, reports. 
No injuries were reported.
The FBI was at the building Tuesday morning to process the scene and review surveillance footage.
“These shootings were cowardly, brazen, violent acts, absolutely without justification and a threat to our entire community,” said Christopher Combs, special agent in charge of the FBI’s San Antonio Division.
FBI officials said at a press conference they were “concerned there could be additional attacks” on federal offices in San Antonio.
