The NYPD has released footage of a suspect wanted in the fatal shooting of a 15-year-old boy in East Harlem.

The man, who was last seen with a cast on his right hand, is being sought in connection to the fatal shooting of Amir James.

James was picking up food with his family when he was shot in the chest by a lone gunman at Lexington Avenue and East 123rd Street around 10:30 p.m Monday.

The teen was pronounced dead at Harlem Hospital.

By early Friday morning, it was still unclear if the teen was targeted or an innocent bystander, according to an NYPD spokesperson.

James’ grandmother, Rosemary West, told The Post in a Tuesday interview that she does not believe her grandson knew his killer.

West described her grandson, a student at Thurgood Marshall Academy, as a top student and a gifted athlete — particularly in football, basketball and kickball.
