The Press Association news agency and others reported that that the 31-year-old rapper was detained early Friday after an incident involving a photographer outside the Tup Tup Palace bar in Newcastle, northern England.
Police said only that a 31-year-old man had been arrested on suspicion of assault after an incident at a nightclub. They said he was later released without charge. British police do not usually identify suspects who have not been charged.
The Tup Tup Palace said West visited the club after his gig in Newcastle Thursday but could not confirm the arrest.
A spokeswoman for West did not immediately return a call seeking comment.
West was arrested last month at Los Angeles International Airport after he was filmed struggling with a paparazzo. He was not charged.
West is playing dates around Britain as part of his Glow in the Dark tour.
