WILMINGTON (CBS) — Authorities say gang members opened fire, wounding two people, at an anti-gang program at Wilmington Recreation Center early Thursday morning.

About 30-people were walking away from the Summer Night Lights program at 325 Neptune Avenue just after midnight when a man in a dark car opened fire on the recreation center.

The Summer Night Lights program was designed to reduce violence during the summer by keeping public parks open for gang-free activity, free food and programs.

Thursday’s shooting is the second at a Summer Night Lights event in as many weeks. A gang member was shot last Thursday by rival gang members in South Los Angeles during a Summer Night Lights event at Van Ness Park, Los Angeles police Sgt. Angela McGee said.
