Madison police recovered a rifle that had been thrown out of a car on Sunday, after witnesses said a person in the car pointed the rifle out the car window.
The incident happened around 11:30 a.m. at Mid Town Road and South High Point Road on the city's West Side, police said.
A 36-year-old Madison man called police after seeing the gun pointed out the window of a car in front of him.
"He and another motorist had been honking their horns, trying to get the car with the armed person inside to move, after it sat for several minutes in front of them at a stop sign," said police spokesman Joel DeSpain.
The car started moving and the witness followed at a safe distance.
"He lost sight of the car but the gun was recovered by police about a half-mile away, in the median of McKee Road at Snowy Parkway," DeSpain said.
No description of the suspect was given.
