A 6-year-old Chicago boy underwent surgery Saturday after he had been shot Friday night while in a car with his mother and two sisters, a family member said.

The boy was struck in the arm by a bullet at about 11:30 p.m. Friday in the 4200 block of West Wilcox Street, near his home in the West Garfield Park neighborhood, Chicago police said. He is the sixth child younger than 8 years old to be shot in Chicago since June 30, according to Tribune records of city shootings.

"It sucks, it surely sucks," said the boy's maternal aunt Cassandra Johnson.

The family was returning home from a trip for food when the boy was shot, said Johnson, who described her nephew as an "average kid" who is fun, outspoken and a fan of basketball.

The boy's mother moved her family to West Garfield Park from the nearby Austin neighborhood about two months ago, after a home there proved too small for the family, said Johnson, who lives in Austin.

Police said it's unclear who the shooter was aiming for, but don't believe the boy's mother or anyone else in the car was a target.

No one is in custody.
