WAYNE, Mich. — A man who opened fire outside a Michigan church filled with worshippers on Sunday was struck by a vehicle and then fatally shot by security staff who averted a potential mass shooting, police said.

Churchgoers attending a morning service at CrossPointe Community Church in Wayne spotted the gunman driving recklessly and then saw him exit his car wearing a tactical vest and carrying a rifle and a handgun, police Chief Ryan Strong said at an evening news conference.

The man began firing as he approached the church, striking one person in the leg.

“A parishioner struck the gunman with his vehicle as the gunman shot the vehicle repeatedly,” Strong told reporters. “At least two staff members shot the gunman, causing the fatal wounds.”
