Authorities are looking for a driver accused of backing over a Livermore Police Department motorcycle, hurting the officer who had to jump out of the way, before speeding away from the scene late Friday morning.

The suspect vehicle was a brown Toyota Tundra crew cab, four-door pickup truck, police said. They did not share a description of the driver nor whether there were other occupants in the truck.

The police officer, who was not identified publicly, was treated for his injuries and released, according to the department.

"This act of violence against our officer is absolutely unacceptable. Our officers put their lives on the line for our community and an attack on an officer is an attack on our community. We will work tirelessly to bring this offender to justice," Livermore Police Chief Jeramy Young said in a statement.

The situation occurred at about 11:45 a.m. Friday when a motorcycle officer was conducting a traffic stop on the Toyota Tundra for an unspecified vehicle code violation on northbound Isabel Avenue between Interstate 580 and Portola Avenue, according to Officer Taylor Burruss, Livermore PD's public information officer.

Burruss said the department has been conducting special enforcement efforts on that stretch of Isabel in the hopes of mitigating the number of car crashes, dangerous driving and speeding.

The driver yielded to the side of the road, but just as the officer began dismounting his motorcycle, the Tundra abruptly accelerated in reverse and backed over the motorcycle, with the truck's tires leaving skid marks on the roadway, Burruss said.

"The officer was forced to jump from his motorcycle into an incoming lane of traffic on Isabel Avenue, narrowly escaping the blatant attack and the potential of being struck by passing traffic. The suspect vehicle backed over the officer’s police motorcycle causing significant damage and rendering it disabled," Burruss said.

Fellow Livermore police officers responded to the scene to tend to the hurt officer and pursue the fleeing truck. The chase was ultimately canceled due to public- and officer-safety concerns, Burruss said.

The Tundra and those responsible remain at-large. Police said they're looking for anyone with information or video of the incident to contact the department's tip line at 925-371-4790 and reference case No. 21-2668. Callers can remain anonymous.
