Sugababes songstress Amelle Berrabah has been arrested after allegedly assaulting an 18-year-old woman on Saturday night.
A 23-year-old female was arrested following an "incident in a bar", police confirmed.
Amelle spent the night in a police cell, according to reports, before being bailed to join the other two Sugababes on a flight to the US.
She joined the British band in 2005, replacing founding member Mutya Buena who left after having a baby.
