ROANOKE, Va. (AP) — Police say a man fatally shot someone and wounded several others inside a rail car manufacturing company in Virginia before apparently killing himself.

Roanoke police spokesman Scott Leamon says the shooting took place around 6 a.m. Tuesday at FreightCar America, located in an industrial area near downtown Roanoke. He says authorities are working to identify the shooter and determine whether he was connected to the company, which has an overnight shift and was open at the time.

Leamon says less than five others were injured. He says he doesn't yet know whether they were shot, but their injuries are not considered life-threatening.

He says officers are searching the facility, but they don't believe there is any threat to the public.
