CUPERTINO — One person was killed in a fatal hit-and-run traffic collision involving a motorcycle on Interstate 280 in Cupertino, an incident that caused part of the freeway to be shut down for hours Saturday, officials reported.

The fatal vehicle crash was reported at 1:19 a.m. Saturday, according to a CHP incident log.

The victim was a motorcyclist who was reported down on the freeway and then was struck by one or more vehicles that were driving past the scene, the CHP reported.

“A motorcycle was struck by a vehicle and the vehicle fled the scene,” CHP Officer Ross Lee said. “The cyclist fell off the bike.”

The deadly accident occurred on southbound Interstate 280 near the North De Anza Boulevard on-ramp to the freeway.

“This is being treated as a hit-and-run,” Officer Lee said. “Several vehicles hit the motorcyclist after he had been knocked down.”

At 1:28 a.m. Saturday, the CHP began to block lanes on the freeway, the incident log states.

Local fire and County Sheriff’s Office units also were dispatched to the scene to deal with the traffic collision.

“We have not released the identity of the victim,” an official with the Santa Clara County Coroner’s Office said Saturday.

The victim was a male, according to the CHP. An age and city of residence weren’t provided as of Saturday night.

The Coroner’s Office said it didn’t expect to release the identity of the deceased victim until at least Monday.

One person was transported to the Coroner’s Office in the wake of the traffic accident, the office said.

At 1:32 a.m., the CHP issued a Sig Alert in connection with the fatal accident.

Some lanes on the freeway were opened at 3 a.m., enabling traffic to proceed in the No. 1 and No. 2 lanes.

All lanes of Interstate 280 were reopened by 4 a.m., Officer Lee said.

“We are asking that anyone who has information about the incident or the initial vehicle that struck the motorcycle rider contact the San Jose office of the CHP,” Lee said.

408-961-0900 is the number that people should contact, the CHP said.
