A police officer on an emergency call broadsided a vehicle at a Minnetonka intersection and killed one person.

The Minnesota State Patrol says Minnetonka Officer Dan Aschenbrener had his squad's lights and siren activated when he collided with a BMW about 9:30 p.m. Tuesday. The State Patrol says the victim was alone in the vehicle and was not wearing a seat belt.

The 28-year-old officer was taken to Hennepin County Medical Center where he was treated for minor injuries.
