NEW YORK (CBSNewYork) -- Two teens were shot inside a fried chicken restaurant in Harlem on Wednesday night.

The 16-year-old and 17-year-old were involved in some kind of dispute before being shot on 116th Street at Fredrick Douglass Boulevard, the NYPD said.

The 17-year-old was shot in the head and is listed in critical condition at a local hospital. The 16-year-old was shot in the back and is stable.

Witnesses described a frantic scene.

"We heard like three shots. We were having dinner right down the block and I saw who I assume was the person who fired the shots round the corner and speed down on 117th," Amanda D'Archangelis said.

Police said a person of interest was taken into custody.
