A 15-year-old boy tonight was arrested in the blow-dart shootings of three men in Brooklyn over the weekend.The teen was being held at the 62nd Precinct and is expected to be charged as a juvenile, law-enforcement sources said.

The random Bath Beach attacks occurred about 7:15 p.m. at 86th Street and Bay 32nd Street, where a 66-year-old man was hit in the stomach and leg, a 51-year-old man was hit in the stomach and a 40-year-old man was hit in the back and leg. The men were not hanging out together at the time.

They were all treated at Coney Island Hospital and released.

In 2003, a man was hit with hit with a blow dart during a drive-by prank in Uniondale, and in 2000, two women were hit with blow darts in Williamsburg.
