Motorcyclist from Cypress killed in Riverside crash

A motorcyclist from Cypress was killed late Saturday night in Riverside when the rider and a flatbed tow truck crashed as the truck was making a turn, police said.

The 54-year-old rider was not further identified until relatives are notified. The crash was reported at Arlington and Hillside Avenues at 9:47 p.m., authorities said.

City firefighters freed the motorcyclist, who was trapped beneath the truck. They tried life support measures on the rider, who died at the scene, the department said.

Police said the tow truck was turning from eastbound Arlington onto northbound Hillside — a left turn — when the collision occurred with the westbound motorcyclist. The incident remained under investigation by police Sunday.
