Police say man deliberately collided into motorcycle officer

A Danville motorcycle police officer suffered minor injuries Monday afternoon in a collision with a Ford Focus that was driven by a man allegedly trying to avoid a traffic stop, police said.

According to police, the officer tried to stop 31-year-old Danville resident Ryan Ohlson for speeding at 1:33 p.m. Monday on Diablo Road and Ackerman Drive.

Police said Ohlson twice tried to collide with the officer on his bike and succeeded the second time at Diablo Road and Alamatos Drive.

Following the collision, Ohlson and his car were found in the Las Trampas Regional Wilderness Park in San Ramon, according to police.

Ohlson was taken to the Martinez Detention Facility on suspicion of evading a police officer, assault of a police officer and hit-and-run.

Earlier Monday, an Alameda County sheriff’s deputy was struck and dragged by a vehicle during an arrest attempt. The deputy was taken to the hospital for injuries to his back.
