A 12-year-old boy was arrested on Tuesday for allegedly attempting to rape a woman in Queens, cops said.

The boy, whose identity has not been released due to his age, has been accused following a 37-year-old woman into her Ridgewood building at Gates and Cypress Avenues around 8 a.m. Monday.

Once inside, the boy allegedly shoved the victim to the floor and attempted to remove her clothing. But the woman fought back and the pre-teen ran out of the building, according to police.

The kid has been charged with robbery, assault, burglary, sex abuse, menacing and criminal possession of a weapon.

Police originally believed the suspect was between 20 and 30 years old.
