FREMONT, Calif. (AP) — Police say a worker at a Tesla factory in California has been arrested on a homicide warrant after a co-worker was fatally shot after a shift.

The male victim was pronounced dead Monday in a parking lot at Tesla’s facility in Fremont.

Police say expended rifle casings were found nearby. Detectives learned that earlier in the day the victim had been in an argument with a potential suspect.

Detectives later arrested 29-year-old Anthony Solima of Milpitas and seized a rifle.

It's not immediately known if Solima has a lawyer to speak on his behalf.

Online Alameda County records show that Solima is being held without bail and is scheduled for arraignment Thursday.
