ICE agent killed, another injured in incident of 'workplace violence'

One immigration agent was killed and another injured Thursday in a shooting in a federal building in Long Beach, south of Los Angeles, officials said.

One agent shot and wounded another, after which a third agent shot and killed the original shooter, officials said in a late-evening press briefing, after earlier reports suggested two agents had died.

"At approximately 5:30 this afternoon (0130 GMT Friday), two agents with US Immigration and Customs Enforcement's (ICE) Homeland Security Investigations (HSI) were shot inside the agency's offices," said an ICE statement.

One of the agents died at the scene, while the second was listed in stable condition in a hospital, it added, saying ICE's Office of Professional Responsibility, local police and the FBI were investigating.

"When something like this happens, it's incomprehensible," said Claude Arnold, head of ICE/HSI in Los Angeles, adding that the wounded agent was shot multiple times.

Long Beach deputy police chief Robert Luna said it was a case of workplace violence.

Steven Martinez, in charge of the FBI's Los Angeles office, said: "This has been a tough day... We will do everything in our power to investigate the circumstances of what occurred here today and provide the facts."
