Authorities say a man suspected of a slaying in Oakland was arrested after sheriff's deputies confronted him for smoking a cigarette in a prohibited area.

The Oakland Tribune reports that 30-year-old Franklin Bean is facing a murder charge in the Dec. 17 killing of Jeremy Johnson. The 25-year-old Johnson was shot outside a store in the city's Fruitvale district.

Authorities say Bean was arrested Friday after two sheriff's deputies spotted him smoking close to a bar in unincorporated Hayward.

A county ordinance prevents smoking within 20 feet of such businesses. The deputies were getting ready to cite Bean when a computer check turned up a warrant for his arrest in the Oakland slaying.

Oakland police say Bean has acknowledged shooting Johnson, but has said he acted in self-defense.
