Baywatch star Jeremy Jackson has been arrested after a man was stabbed in the chest with a knife.
The attacker was allegedly identified as "Hobie" from the hit show.
Jackson was taken into police custody on Saturday for assault with a deadly weapon in West Lake, Los Angeles.
The 34-year-old is accused of stabbing a man with a knife on Friday. His relationship to the man is not clear.
The victim told police the man was "Hobie". Jackson played Hobie Buchannon, the son of David Hasselhoff's character Mitch Buchannon on Baywatch.
On Saturday, police received a report of a possible prowler in the same neighborhood where the attack took place, reports the LA Times.
Officers stopped that alleged prowler and discovered it was Jackson - who was wanted in the stabbing. He was arrested at 7.15am.
Jackson was released that same day on US$30,000 bail, according to the Los Angeles County Sheriff's Department.
Jackson, of Newport Beach, California, has not addressed the arrest on social media.
He is well-known for his troubled personal life.
He left Baywatch, which he starred in from 1991-1999, because he was suffering from a severe drug addiction, according to an interview with E! on Child Star Confidential.
And in 2011 he was treated for steroid addiction on Celebrity Rehab with Dr Drew.
In January, the former child star was kicked out of UK reality show Celebrity Big Brother for groping a glamour model in a drunken stupor - he was later cautioned by police.
And earlier this year the former Baywatch star was alleged to have attempted to murder his ex-wife in an attack caught in a terrifying audio recording.
