An SUV driver ran a red light, struck a bicyclist early Sunday morning at a well-traveled intersection in downtown St. Paul and fled the scene, leaving the victim fighting for his life, authorities said.

The collision occurred about 12:10 a.m. Sunday at W. 7th Street and Grand Avenue, according to police.

Officers arrived to find the cyclist in a lane of traffic on westbound W. 7th, police said.

"The victim was unconscious, unresponsive and suffering from grave injuries," a statement from police read. He was taken by Fire Department paramedics to Regions Hospital, where he was in critical condition late Sunday.

Authorities have not identified the bicyclist and are trying to locate anyone who might know his name.

Police say they are looking for the driver of the tan or beige SUV and the vehicle, which likely has front-end damage. The SUV fled west on 7th, said police spokesman Steve Linders.

Anyone with information about the vehicle, its driver or the victim's identity is asked to call police at 651-291-1111.
