King, 36, was arrested Saturday following a traffic stop near a Pomona park. King allegedy was under the influence of P-C-P.
He was a passenger in a vehicle near the park driven by an unidentified woman, Pomona police Lt. Dave Keetle told the Inland Valley Daily Bulletin.
Officers had responded to a report that King was bothering people, jumping on an ice chest and exposing himself to others.
King, of Altadena, was at Pomona Valley Hospital Medical Center Saturday night, waiting to be medically cleared before being transferred to Pomona City Jail.
He is scheduled to be arraigned in Pomona for another misdemeanor drug charge stemming from an Aug. 28 arrest.
King has twice spent 90 days in jail for misdemeanor domestic abuse convictions in the past few years.
He remains on probation in San Bernardino County for a March 1999 incident in which he admitted abusing the mother of his teen-age daughter in Fontana.
In March 1991, television stations broadcast an amateur videotape of LAPD officers clubbing the unarmed King. Replayed again and again, the short, brutal clip riveted the nation and became an instant symbol of racism and police brutality in America.
The acquittal of four officers of state charges for the beating led to massive riots, destroying much of South Central L.A.
Two of the officers were later convicted in federal court of violating King's civil rights.
King also won a $3.8 million settlement in a civil rights lawsuit against the city of Los Angeles.
