UPDATE ON DEC. 14: The name of the cyclist has been released, and authorities have released information about the driver admitting to marijuana use hours before the crash. Read the latest story here.

Portland police have arrested a 26-year-old driver who they say was high on marijuana when he killed a bicyclist in Northeast Portland Saturday evening.

Police have not yet released the name of the 38-year-old male cyclist, pending the notification of his family.

Police say Kenneth Britt Smith crashed his 2000 Ford Crown Victoria into the cyclist from behind at about 8:38 p.m. in the 4200 block of Northeast Lombard Street, which also is called Portland Highway.

The cyclist was wearing a helmet and the rear of his bicycle was equipped with a flashing red light, police say. The cyclist died on the scene.

Smith didn't stick around, police say. He was arrested eight minutes after the crash, after police spotted his car about three miles away at Northeast 97th Avenue and Killingsworth Street, said Sgt. Pete Simpson, in a news release.

Police booked Smith into Multnomah County jail on accusations of second-degree manslaughter, criminally negligent homicide, reckless driving and driving under the influence of intoxicants.

If found guilty of the most serious charge -- second-degree manslaughter -- Smith faces at least six years and three months in prison.
