Passionate fans of Ariana Grande are urging that a individual who breached a barricade and touched the actress during the recent Wicked: For Good launch be taken into custody or deported from Singapore.
A circulating clip shows the Australian man bypassing camera operators and lunging at Grande while the performers proceeded down a yellow carpet flanked by fans.
Cast member Cynthia Erivo quickly wrested the stunned actress away from Mr Wen, who was spotted being escorted out of the premiere by guards.
Mr Wen stated on Instagram late on Thursday that he was "released after being taken in", though official papers revealed that he was set to appear on the next day. It is unknown if he was faced legal action.
This is part of a pattern for Mr Wen, who describes himself as a "Controversial Figure", has crashed a performance. His Instagram feed includes clips of him disrupting other star-studded functions, including breaching the performance area at the pop singer's Sydney show in June this year and in a similar way during The Chainsmokers event in the city last year.
"Steps should be implemented enforced against him as this is evidently a criminal offence," wrote an Instagram user, in a message to a video Mr Wen shared of his behavior.
"You've done this repeatedly... how are you not behind bars?" another Instagram user wrote.
Many fans blamed Mr Wen for "re-traumatising" Grande, who had discussed suffering from trauma-related anxiety after a suicide bomb attack at the conclusion of her 2017 show in Manchester, killing 22 people and wounding numerous individuals.
"After everything she's faced... including the Manchester attack, you considered it entertaining to rush the barrier?" wrote one more comment on Instagram.
Some supporters also criticised event staff at the Thursday event for not being sufficiently alert; while some requested social media platforms to block Mr Wen's videos.
In footage spreading on the internet, Grande seemed shocked when she was grabbed by the man. Her fellow actors Michelle Yeoh and Erivo can be spotted consoling her while Mr Wen was escorted away by guards.
Grande has remained silent on the incident, and the remaining proceedings carried on uninterrupted.
Hundreds of attendees had congregated in a sea of green and pink at the Wicked: For Good Asia-Pacific launch in a Singapore mall, including some who had queued for as long as many hours before it commenced.
The film, to be launched on November 21, is the sequel of a two-part adaptation of the acclaimed theatrical production Wicked, which centers on the unlikely friendship between two distinct witches.
The production itself is a adaptation of the twentieth-century book The Wonderful Wizard of Oz.
Grande, who plays the benevolent sorceress Glinda, was adorned in a rosé sparkling outfit at the premiere while Erivo, who acts as the wicked witch, wore a sleek black dress featuring roses.
They were joined by co-star Jeff Goldblum.
The first movie, Wicked, was the most successful movie of the previous year in the UK, and earned a dozen Oscar nominations, earning a pair for best costume and production design.
