Corrections parole agents attempting to arrest a parole violator shot the man on Huntington Drive in Duarte around 2:30 p.m. Friday.
According to Luis Patino, a spokesman with the California Department of Corrections and Rehabilitation (CDCR), the violator pulled a knife and threatened one of the agents, causing the officer to open fire.
Samuel Castro, 20, is in serious condition and undergoing surgery at a local hospital. All agents were unharmed.
Castro, a wanted fugitive, had been suspended from parole for failing to report to his agent this Wednesday, says the Los Angeles Sheriff's Department.
He last served time in Corcoran State Prison for assault with a deadly weapon resulting in great bodily injury. He'd been sentenced to four years.
Agents had received information that Castro would be at the 1900 block of Huntington Drive in Duarte, and when the team saw him walking along the road they assigned an undercover operative to do a "walk-by" — to walk by the subject and confirm his identity. It was during this walk-by that Castro pulled a knife and was shot in response.
Agents on the scene administered first aid until responders arrived.
