Former 49ers and Raiders offensive lineman Kwame Harris was arrested Sunday night in San Francisco after police said he was involved in two hit-and-run collisions while on drugs, fell asleep in a running vehicle and tried to bite the hand of a responding officer.

The incident began when officers on patrol were flagged down near 14th Street and South Van Ness Avenue around 7:30 p.m. and told of a man in a car needing assistance, said Officer Grace Gatpandan, a police spokeswoman. She said they found Harris, 33, of San Francisco, asleep in a vehicle parked halfway into a chained-off driveway.

Police woke the sleeping Harris, who was groggy and unresponsive, Gatpandan said, leading officers to suspect he might be under the influence of drugs or alcohol. Because the car was running and there were pedestrians in the area, officers tried to handcuff Harris, Gatpandan said. He resisted, at one point attempting to bite the hand of one of the officers before being subdued, police said.

Medics called to the scene determined Harris was high, Gatpandan said. He was arrested on suspicion of driving under the influence, aggravated assault on an officer, hit-and-run and resisting officers.

Investigators came to suspect Harris in two hit-and-run crashes earlier in the evening. The first, near the intersection of Hyde Street and Broadway, involved a silver sedan, and the second, on the 1700 block of Harrison Street, involved a recreational vehicle, Gatpandan said.

Harris, who attended Stanford, was the 49ers’ first draft pick in 2003 and played five seasons for the team before signing with the Raiders. He played the 2008 season with Oakland, then was released and has been out of football since.

In 2013, Harris was convicted of misdemeanor domestic abuse and assault for beating up his then-boyfriend after a verbal dispute over soy sauce and stolen underwear at a Menlo Park restaurant.
