ORINDA — Police are seeking charges against the parent of a teenager who hosted an alcohol-fueled party and against a partygoer's parents who tried to cover up a DUI crash that followed, police said.

Seven Miramonte High School students were arrested and cited after Orinda and Lafayette police responded about 12:30 a.m. Sunday to a house party in the 4100 block of Happy Valley Road.

Four of the teenagers, including the party host, were arrested on suspicion of public drunkenness; two on suspicion of driving while intoxicated; and one on suspicion of possessing marijuana. The host also was cited for holding an unruly party. All were released to their parents.

Orinda police Chief Bill French said one of the teens arrested on suspicion of DUI also is suspected of hit-and-run after striking a parked car and then shearing a telephone pole while leaving the party.

Police are seeking charges against the parent of the host for allowing the party to happen. Police also are asking the district attorney's office to file charges against the parents of the teen who crashed into the telephone pole, arguing that they interfered with police by taking the teen away from the crash site and being evasive with investigators who contacted them.

"They were obstructing our investigation," French said.
