A caller told the LAPD that an armed former employee of Homeboy Industries was possibly holding six to eight hostages at or near the building on the 100 block of Bruno Street. Officers, armed with rifles, entered the building around 10:30 p.m. Thursday, but they didn't see any signs of a suspect. They issued an all-clear in the area and started reopening streets around midnight.
Then around 2 a.m. Friday, officers were back at the scene after employees thought they saw the suspect sitting in a vehicle. Police determined that the person in the vehicle was not the suspect.
Authorities do not believe anyone was taken hostage, but they are still looking for the suspect. Police say they know who they are looking for, but did not release a suspect's name.
Investigators said they are interviewing witnesses and reviewing surveillance video.
Homeboy Industries is a gang-prevention and job training agency.
