RIALTO, Calif. (AP) _ Rodney King has been arrested for allegedly punching his girlfriend, less than two months after he was sentenced for driving under the influence.

King, whose videotaped beating by police officers sparked the Los Angeles riots of 1992, was booked for investigation of domestic violence on Saturday and released Monday on $50,000 bail, a records clerk at the West Valley Detention Center in Rancho Cucamonga said.

King's girlfriend called police Saturday and said he punched her in the stomach and tried to choke her during an argument that began the previous night, Rialto police Sgt. Shawn O'Connell said.

King, 38, of Rialto, was pulled over and beaten by officers in 1991. After a jury acquitted the officers the following year, riots broke out across Los Angeles, leaving 55 people dead, more than 2,000 injured and $1 billion in property damage.

King received a $3.8 million settlement from the city of Los Angeles in 1994. Since then, he has had a series of run-ins with the law, including a 1999 domestic violence conviction.

On Aug. 27, King pleaded guilty to driving under the influence and was sentenced to a three-month alcohol awareness program and six months of drug treatment, followed by four months in jail.

King's lawyer Duane Dade was in court Tuesday and didn't immediately return a telephone message left at his office.

The San Bernardino County District Attorney's Office hasn't reviewed the latest arrest.

``If he's on probation, then we would have a hearing,'' District Attorney Michael A. Ramos said. ``I don't know what the situation is. But we take all these matters seriously.''

Rialto is about 60 miles east of Los Angeles.
