DENVER (AP) -- Denver police say four people who were struck in a hit-and-run accident after a disturbance over the weekend were innocent bystanders.

Authorities say a disturbance in the Maxim Lounge parking lot around 2 a.m. Sunday spilled into the street, and a vehicle sped through a parking lot and hit four pedestrians who weren't involved in the fight.

Police said Monday that a husband and wife are still hospitalized in critical condition. Another man also was injured, and a woman who walked away from the scene was later diagnosed with a concussion.

Investigators describe the suspect's vehicle as a silver Honda Civic hatchback with tinted windows and damage on the driver's side front end.
