A creep pounced on a woman and grabbed her buttocks in a disturbing caught-on-video incident this week in Brooklyn.
The 35-year-old victim was walking south on Morgan Avenue in Williamsburg at 8:10 p.m. Monday when she noticed a stranger was following her, according to police.

She turned to head west on Stagg Street, but he still trailed behind — and then sped up, tackling her onto the ground, footage released by cops early Thursday shows.
The man held her down, reached into her shorts and grabbed her buttocks, the video shows.
Then he took off running east on Stagg Street.
The victim did not report any injuries and refused medical treatment.

The suspect is around 5-foot-5, weighing 165 pounds, with a medium complexion, medium build and black hair, police said.
He was last seen wearing a black T-shirt, green camouflage pants and black sneakers.
