Johannes Mehserle ARRESTED IN NEVADA

(CNN) -- The former police officer accused of shooting an unarmed man at a northern California commuter train station was arrested Tuesday in Nevada, authorities said
Former Bay Area Rapid Transit officer Johannes Mehserle was arrested on a fugitive warrant charging homicide.

Mehserle is accused of the shooting of Oscar Grant III at an Oakland, California, station on New Year's Day. The incident was captured on video by several witnesses and spurred violent protests in the northern California city.

Mehserle, 27, was taken into custody in Douglas County, Nevada at about 7 p.m. (10 p.m. ET), Sgt. Dan Coverly of Douglas County Sheriff's Office told CNN affiliate KGO-TV in San Francisco.

Mehserle resigned from his job as a BART police officer days after the shooting. The transit agency's police force and Alameda County District Attorney Tom Orloff are investigating the incident.

Grant, a 22-year-old father, was killed on New Year's Day in a crowded BART train station. Police had been called to the Fruitvale station after passengers complained about fights on a train and took Grant and several other people off the train once they arrived.

Videos from witnesses show Mehserle shooting Grant in the back as another BART officer kneeled on the man. The shooting spawned public outrage and a string of protests that led to more than a hundred riot-related arrests.

Police have not said whether Grant had been involved in the fight.

Referring to Mehserle's arrest, BART said, "This comes after the BART Police Department conducted a thorough investigation that involved nine detectives, which BART Police turned over to District Attorney Thomas Orloff on Monday, Jan. 12."

Leads led investigators to Mehserle in Zephyr Cove, Nevada. Contacted through his attorney, Mehserle surrendered. He was taken into custody at 6:20 p.m. PT without incident.

Jail staff report that Mehserle has cooperated and is in a segregated area and on a precautionary health and welfare watch.

The Oakland Police Department is running its own investigation into the killing, at the request of Mayor Ron Dellums, Officer Jeff Thomason said Wednesday
