MISSOULA, Mont. - Authorities are investigating a scene at Toole Avenue and Broadway in Missoula after reports of shots fired.

According to the Missoula County Undersheriff Rich Maricelli, three suspects are in custody and one man was taken away in an ambulance after a single shot was fired in a vehicle.

When officers caught up with the vehicle involved at the Zip Trip gas station, they saw a gun and took cover, said Maricelli.

Because officers were on the scene when the shot was fired, Ravalli County Sheriff's officials are coming to Missoula to investigate.
