MINNEAPOLIS (AP) — Authorities say a suspected drunken driver rammed an unoccupied Minneapolis police cruiser head-on before surrendering to authorities.

The Star Tribune reports there were no injuries in the Saturday morning incident, which happened after officers had responded to a report of a person with a gun. The officers were returning to their vehicle after the investigation when the accident happened.

Police say a 27-year-old Minneapolis woman was arrested on suspicion of drunken driving after refusing a breathalyzer test. Other charges are possible.

Both vehicles sustained severe front-end damage and were impounded.
