A pair of armed robbers stormed into a Bronx barber shop Friday night and stole the barber’s jewelry as he worked on a customer, cops said.

The suspects were shown strolling up a Pelham Bay sidewalk near Manuel’s Style Barber Shop on Buhre Ave. near Hobart Ave. before the 8:30 p.m. heist, surveillance footage shows.

A witness in the barber’s chair sat motionless as a suspect described by police as a 6’2” black male wearing grey sweats brandished a gun in his waistband and grabbed at the barber’s chain necklace.

He then yanked at the 29-year-old barber’s bracelet, which fell to the ground amid tufts of hair as a second suspect, described as a 5’8” black male wearing camouflage pants, watched.
