A gang of nearly 20 teenagers beat and robbed a 15-year-old girl in an attack caught on camera in Brooklyn on Thursday.

The incident was captured by security cameras and released to the public by the NYPD.

The girl was walking in front of 216 Utica Avenue at 4.10pm when she was attacked.

In the video, she is seen running away from the teenagers before falling and brutally attacked by the group.

Her shoes, debit card and phone were stolen, according to assistant chief Jeffrey Maddrey, commanding officer of the NYPD.

He condemned the attackers on his Twitter feed, insisting that this sort of behaviour is not acceptable.

“OUTRAGE:this is sickening video of a 15 year old girl viciously attacked by a group of school children. One young man takes the sneakers right off the unconscious victim’s feet. The teenager is in the hospital recovering. We CAN NOT allow this behaviour in our community. #Speakup” he tweeted.

The NYPD released their February crime statistics on Thursday, showing that both assault and robbery are up from the same period in 2019.

Assault was up from 1,294 to 1,413, a 9.2% increase while robbery was up from 891 to 1,182, a 32.7% increase.

The police said that she was taken to NYC Health & Hospitals/Kings County and was treated for bruising and head trauma.
