An off-duty NYPD cop was busted for allegedly groping a woman inside the Hard Rock Cafe at Yankee Stadium after a game Sunday, authorities said. 

Officer Julio Alcantara-Santiago, 38, was inside the eatery around 11 p.m. when he touched the breast of a 52-year-old woman he didn’t know without permission, cops said. 

Alcantara-Santiago was arrested and charged with forcible touching and sexual abuse. 

The cop, who has been with the NYPD for about 10 years, was suspended without pay, officials said.
