A violent group of strangers pummeled and robbed a woman in Brooklyn late Thursday, disturbing new video shows. 

The 46-year-old was walking on Broadway near Roebling Street in Williamsburg around 11:50 p.m. Thursday when the group of six suspects approached and started throwing punches, according to police. 

The flurry of punches began on the sidewalk, but continued on the street, where the victim fell to the ground, according to the clip, posted by the Williamsburg News Twitter account.

Some of the violent group – who appear to be both men and women – kicked the victim when she was down on the ground, the clip shows. 

They grabbed the victim’s purse, containing a cell phone, wallet, $25 and bank cards, police said.

The victim suffered non-life-threatening injuries and was taken to Woodhull Medical Center, where she was listed in stable condition. 

A man standing next to a CitiBike looks on through the entire ordeal and doesn’t assault the victim, but then is shown leaving the scene with the crew — who cops say fled east on Broadway.

A car passed down the block, as did a pedestrian on foot, during the late-night mugging, the clip shows. 

No arrests had been made by Friday afternoon.
