Red Line stabbing suspect arrested

A transient sought in a fatal stabbing on the Metro Red Line in Hollywood has been arrested, authorities said Wednesday.

Gene Sim, 33, was taken into custody Tuesday night in Buena Park, officials with the Los Angeles County Sheriff’s Department said.

Sim was booked in connection with a probation violation and was being held without bail. He was described by sheriff's officials as a transient.

Murder charges against him are pending, said Sgt. Diane Hecht, who was unsure of the exact nature of his alleged probation violation.

The stabbing took place Friday just before 7:30 p.m. Witnesses, including a Los Angeles Times staff writer, said a confrontation broke out on the crowded train when a man began swinging a chain at a younger rider.

As they argued, the younger man pulled out a knife and stabbed the chain-wielding man, witnesses said.
