The Richfield Police Department says officers responded to a report of a person down in the street on southbound Nicollet Avenue north of 66th Street just after 1 a.m.

Upon arrival, officers found the victim — 56-year-old Lavelle Maurice Harris, of Minneapolis — who had been struck by a vehicle. He died on the scene.

Police arrested a 40-year-old Richfield man under suspicion of driving while impaired and criminal vehicular operation.

Investigators say they do not believe Harris had been in the crosswalk at the time of the incident.

The crash remains under investigation.
