A 20-year-old man was shot and seriously wounded near a CTA train station on the city's Far North Side.

The shooting happened about 3:30 a.m. in the 1600 block of West Howard Street, police said. They initially believed the shooting happened in the 7500 block of North Paulina Street.

Police said the victim was walking down the street when a passing car slowed and the people inside asked the man his gang affiliation, said Officer John Mirabelli, a police spokesman.

The man said that he had none, prompting one of the men inside the vehicle to get out and open fire in the man's direction, Mirabelli said.

The man, who was struck in his left side, then staggered to the Red Line's Howard station, authorities said.

He was taken to nearby St. Francis Hospital in Evanston in serious condition.

Police were searching for as many as six suspects, some with facial tattoos, who fled in a white SUV or minivan, but lacked detailed descriptions.

No arrests had been made.
