Police are hunting for a serial rapist in the Bronx who climbs through his victims’ windows.

The suspect has struck twice, each time using a fire escape to gain entry, police said.

The attacker first struck at 1:30 a.m. on Nov. 6, when he climbed up into an apartment on Taylor Avenue and forced a 20-year-old woman to touch his genitals before fleeing, police said.

Earlier this month, the same creep scrambled up a Thieriot Avenue fire escape just blocks away from the first attack.

He entered a woman’s bedroom, flashed a gun and demanded cash before raping the 28-year-old victim and running down the fire escape, police said.

Authorities are extensively canvassing the area for any information leading to the rapist, who is described as approximately 5-foot-7 and 200 pounds.
