A Singapore anime convention has sparked online controversy after aviral altercation involving internet personality Amos Yeeand a cosplayer dressed as Yuji Itadori triggered confusion and fast-spreading speculation across social media.

The incident, captured on multiple mobile phones and widely shared online, shows a brief physical confrontation outside a major anime event venue in Singapore. The footage quickly circulated, fuelling early speculation and fragmented accounts of what had taken place.

Police later confirmed that ateenage cosplayer was detainedfollowing the incident on suspicion of public nuisance and possible assault-related offences. Investigations into the circumstances of the confrontation are ongoing.

As reported by Malay Mail, Singapore police confirmed the arrest of a teen cosplayer in connection with the incident at the anime convention, with authorities continuing to examine the events leading up to the altercation.

Amos Yee first came to prominence in Singapore in 2015 as a teenage blogger and YouTuber after posting controversial videos criticising the late founding prime minister Lee Kuan Yew and religious institutions.

His content triggered widespread backlash and led to multiple arrests under Singapore's laws relating to religion, obscenity and public order.

Yee later left Singapore and was granted asylum in the United States, a case that drew international attention and debate over free speech and political expression.

His public profile shifted again after he was convicted in the United States on child-related sexual offences. He was later deported back to Singapore in 2026.

Since his return, Yee has remained a polarising figure, frequently resurfacing in online discussions linked to his legal history and previous activism.

The incident occurred near a large-scale anime convention in Singapore over the weekend, where attendees witnessed a sudden altercation between Yee and a teenager dressed as Yuji Itadori from the anime Jujutsu Kaisen.
