A bicyclist was critically wounded after being hit by a car Saturday night on the Near West Side.

A man, whose age wasn’t immediately known, was riding his bike in the 900 block of West Madison Street about 10:10 p.m. when he was struck by a silver sedan, Chicago police said.

He suffered trauma to the body and was taken to Stroger Hospital, where he was in critical condition, officials said.

The driver of the sedan, a 30-year-old woman, attempted to drive away, but was stopped by nearby pedestrians, police said. Authorities say she was suspected of being under the influence of a controlled substance.

She was taken into custody by officers.

Charges were pending.
