Three baby-faced suspects robbed a 12-year-old boy at gunpoint in the Bronx last week, cops said early Wednesday. 

The pre-teen was standing on West 167th Street near University Avenue in Highbridge around 8:20 p.m. when the trio approached him, police said. 

One of them flashed a gun while the other two grabbed the boy’s sweatshirt and backpack, cops said. 

The crew — shown in surveillance footage released by the NYPD — then fled on foot, police said. 

No arrests have been made.
