Police are searching for a man who dragged an 11-year-old girl into a Queens alley last weekend and spewed sexual threats before fleeing with her belongings.

The brute attacked the victim as she was walking near 86th Street and Northern Boulevard in Jackson Heights at about 8:45 a.m. on Sunday, according to cops.

After forcing her into an alley, the man threw her to the ground and held a sharp metal object to her throat while making sexual threats and demanding to know her age, police said.

The attacker stole the victim’s house keys, $20, a reusable grocery bag and then fled on foot northbound on 86th Street, cops said.

The girl suffered a cut to her throat and was treated at a local hospital.
