Shocking footage shows a white woman go on a rampage and attack a black teenager, who she has wrongly accused of stealing her iPhone.
The woman left her phone in the back of an Uber and then accused 14-year-old Keyon Harrold Junior of taking it, in a dramatic incident recorded on CCTV in the lobby of Arlo Soho hotel, New York city, on December 26.
In the clip, the angry woman lunges at the kid and wraps her arms around him, clinging onto him while he tries to escape her grasp.
They then barrel through the hotel, with the lad eventually toppling to the floor with the woman on top of him.
Junior's dad, Keyon Harrold, tried to defend his son from the woman, who he called a "lunatic" on social media.
He "sustained scratches to his hand", New York City Police Department said.
In another video, uploaded by the dad on social media and apparently showing the argument before the assault, the woman shouts: "Show me my phone!"
The hotel manager also asks to see Junior's phone in the minute-long clip, which cuts out just as the woman is advancing towards the teen and the dad yells: "Get your hands off!"
Police said they have "positively identified" the woman in the footage but have not released her name to the public and the altercation is not being investigated as a bias incident.
Arlo hotel released a statement on Twitter apologising for the staff member taking the woman's side of the story, admitted the innocent lad experienced "prejudice".
It said: "We're deeply disheartened about the recent incident of baseless accusation, prejudice and assault against an innocent guest of Arlo hotel.
"In investigating the incident further, we’ve learned the manager on duty promptly called the police regarding the woman's conducting and that hotel security intervened to prevent further violence; still more could be done to deescalate the dispute.
"No Arlo guest — or any person — should be subject to this kind of behaviour.
"We want to apologise to Mr Harrold and his son for this inexcusable experience and have reached out to them directly to express our sincere regret and offer help dealing with this traumatic event.
"In investigating the incident further, we've learned the manager on duty promptly called the police regarding the woman's conducting and that hotel security intervened to prevent further violence; still more could be done to deescalate the dispute.
"We are committed to making sure this never happens again at any of our hotels," the hotel said.
