US singer Chris Brown has been denied bail by an English court over a serious assault charge, throwing his upcoming world tour into doubt.
Brown has been charged with inflicting grievous bodily harm in what prosecutors said was an "unprovoked attack" in a London nightclub in 2023.
The 36-year-old has not yet been asked to enter a plea to the charge.
His tour manager and record label did not immediately respond to a request for comment.
Brown was arrested at a hotel in Manchester, northern England this week after returning to the United Kingdom.
Prosecutor Hannah Nicholls told Manchester Magistrates' Court on Friday that Brown had committed an "unprovoked attack with a weapon in a nightclub full of people".
She added that Brown allegedly attacked a music producer with a bottle at the Tape nightclub in central London on February 19, 2023.
The R&B star, a two-time Grammy Award winner known for hits such as Loyal, Run It and Under the Influence, is set to kick off his Breezy Bowl XX tour on June 8 in the Netherlands.
Judge Joanne Hirst remanded Brown into custody ahead of his next appearance at London's Southwark Crown Court on June 13.
