Four teens shot near park in Brooklyn: Officials

At least four teenagers were shot Monday night at a park in Brooklyn, officials said.

Gunfire erupted at about 6:30 p.m. in Ocean Hill near Herkimer Street and Thomas S Boyland Street, officials said. A 16-year-old boy was shot in the arm and transported to Brookdale University Hospital, according to police and fire department sources, and three other teens -- two boys, 16 and 18, and a teenage girl -- were grazed by bullets and taken to area hospitals. All are expected to survive.

Cops were looking for the gunman last night, believed to be a teen who fled on a bicycle.
