A Lyft driver was arrested in Elm Grove early Saturday after passengers said he pointed a handgun at one of them and threatened to "blow your head off."

The suspect is a 47-year-old Milwaukee man, according to a post on the Elm Grove Police Department's Facebook page. It said the man was in custody at the Waukesha County Jail on charges of endangering safety by use of a dangerous weapon and intentionally pointing a firearm at another.

According to police, the incident occurred around 10:30 p.m. Friday in the 13200 block of Watertown Plank Road after two employees of the Silver Spur requested a Lyft driver. They were in the car when an argument ensued over a U-turn.

The passengers told police they got out of the car and that the driver nearly hit one of them. They said the driver then brandished a black handgun while racking the slide, pointed the gun at the caller's head and stated, "I'll blow your head off you ..." before fleeing.
