A man in Oklahoma City is wanted after allegedly throwing an inert grenade into a moving Amazon delivery van and forcing the driver to bail out on Monday, authorities said.

The incident happened around 3:30 p.m. in the 500 block of Southwest 27th Street, Oklahoma City police said in a police report provided to Fox News Digital.

The driver told police he was delivering packages when he spotted a man walking along the sidewalk. He said that he had the van’s sliding door open when he heard something hit the floor in the rear of the vehicle and noticed what looked like a grenade.

With the van still in motion, the driver said that he jumped out "without even thinking about it" and sustained minor injuries to his knees after landing in the street. He said the van continued moving until it crashed into a mailbox and a parked car.
