The NYPD says a shooting at a basketball court in Brownsville has hospitalized three men.

Investigators say a 23-year-old man was shot in his leg, a 24-year-old man was shot in his leg and another 24-year-old man was shot in his arm at around 9 p.m. at the Kennedy King Playground on East 93rd Street.

Two of the men were taken to the hospital by EMS, while the third man walked into a hospital for treatment.

Police say they recovered 13 shell casings from the scene. Authorities are still trying to determine if the men were shooting at each other or if a separate suspect is involved.
