A 13-year-old boy playing in a Brooklyn park Sunday became the 10th New York City child to be shot in September, suffering an arm wound from a bullet fired by a drive-by attacker, police said.

The shooting took place at 4 p.m., when a car moved by a group of children playing in a park, and an occupant fired two shots, one striking a youngster in the upper arm.Police said the 13-year-old victim, who was not identified, was taken to Brookdale Hospital, where he was listed in stable condition.

"There's no reason to believe (the occupant of the car) was shooting at this kid," said police spokesman Sgt. Ed Burns. "It appears to be random."

No one else was injured in the incident, Burns said.

The boy was the 24th child to be struck by gunfire in the city since July 22 and the sixth in the past 10 days.

Eight of the young victims, including a 3-week-old boy and two 13-year-olds shot last week, have died.
