A bicyclist was critically wounded after he was struck by a vehicle Friday in the Gold Coast.

He was riding eastbound about 2:20 a.m. on Oak Street when he failed to stop at a red light and was struck by a male northbound in a GMC SUV in the 1000 block of Michigan Avenue, Chicago police said.

The 22-year-old man was taken to Northwestern Memorial Hospital in critical condition, police said.

No citations were issued, and Chicago police’s major accidents unit is investigating.
