Chinese police on Sunday said they've detained a 30-year-old Canadian man surnamed Wu on suspicion of rape.
State media has identified the man as Chinese-born pop singer Kris Wu.
The singer, who was previously a member of the K-pop group EXO, was under investigation over accusations made online, of quote "tricking young girls into having sex with him," according to a statement by Beijing police.
An 18-year-old Chinese student publicly accused Wu last month of luring her and other girls, some under the age of 18, to have sex with him.
The student told Chinese media she was 17 at the time of the incident and was pressured to drink alcohol and have sex with him.
A police statement said the student was invited by Wu's team to his house for a music video casting Wu has previously denied the accusation and was not immediately available for comment on Sunday.
His studio did not respond to a request for comment and his law firm did not answer calls.
It was not immediately clear if Wu's arrest was linked to the student who made the accusations in July.
At least a dozen brands, including Porsche and Bvlgari, have cut ties with Wu since the allegations.
