YouTuber Kai Cenat is in custody after a game console giveaway sparked chaotic scenes in Manhattan’s Union Square – with police urging people to avoid the area.
Thousands of people gathered on Friday afternoon for the event organised by popular Twitch streamer and YouTube content creator.
The giveaway was expected to include PlayStation 5 consoles.
Video footage from the scene showed chaos erupting, with people hurling objects, throwing punches, scaling structures in a park and pushing over a number of barriers.
People were also filmed running through the streets, climbing on top of a moving car and pounding the side of a city bus.
The New York Police Department said there have been numerous other arrests from the crowd.
They advised people to stay clear of the area and warned drivers should expect delays during rush hour.
More than 1,000 officers were called to attend the scene, NBC reported.
Using loudspeakers they warned crowds: “This gathering is unlawful. You are ordered to disperse.”
Numerous people were seen in handcuffs, but there have been no reports of significant injuries.
Many trains on the subway were also avoiding the Union Square stop in both directions due to “activity at that station”.
Cenat, 21, who has millions of followers on social media, promoted the event with an image on Twitter.
His YouTube videos, which have amassed more than 276m views, range from videos of his daily life to comedy vlogs. His most recent was titled “I Rented Us Girlfriends In Japan!”
