Swedish prosecutors have requested that ASAP Rocky be formally arrested for his alleged involvement in a fight and be detained while they investigate the incident which could take up to two weeks.

Rocky is scheduled to perform Sunday at Wireless Festival in London, but prosecutors feel that both the rapper and his two bodyguards could "obstruct justice if freed."

Rocky was detained late Tuesday night by Swedish police on suspicion of assault after a video was posted showing the rapper and three others involved in a street fight. 

"So a few drug addicts are not my fans," the rapper captioned in a video of the incident which he shared on his Instagram page. "We don't know these guys and we didn't want trouble, they followed us for 4 blocks, and they were slapping girls butts who passed, give me a break."

He claimed that the alleged victim hit his security guard in the face with a pair of headphones.
