This creep’s early morning buzz may get him busted.

A Brooklyn woman chased down and photographed this beer-swiller after he slapped and grabbed her buttocks as she was crossing the street, police said Thursday.

The 25-year-old woman was crossing 86th Street and Gatling Place in Bay Ridge at 9 a.m. Nov. 5 when the stranger passed her, smacked her butt and squeezed it — all while holding a can of Budweiser in his other hand.

She followed the man and began snapping photos of him in front of a nearby P.C. Richard & Sons as he smirked and tried to cover his face with his free hand.
