A male bicyclist in his 50s was fatally struck Monday evening by a motorist who was allegedly driving drunk, police said today.

The crash happened around 6:30 p.m. on Bolsa Chica Road north of Heil Avenue, Lt. Bo Svendsbo of the Huntingon Beach Police Department said. The victim was identified by coroner's officials Tuesday as 55-year-old Michael Peter Bastien.

The cyclist was heading southbound on Bolsa Chica when he was struck by a Mercedes Benz sedan driven by an unidentified male suspect, Svendsbo said. Both men were Huntington Beach residents.

Bastien was taken to a hospital where he was pronounced dead from his injuries, the lieutenant said.

The suspect was arrested for drunken driving, but an investigation was ongoing to determine if he should face any additional counts, Svendsbo said.
