Three people, including a 14-year-old girl, were shot last night inside a Brooklyn catering hall that was hosting a baby shower, cops said.

The victims were wounded inside Universal Resort on Church Avenue near East 48th Street in East Flatbush, around 9:30 p.m. in a possible robbery attempt.

The teen was struck in the chest. A 34-year-old woman and an unidentified man were also shot. They were all expected to survive.
