Hibernian goalkeeper Graham Stack has been arrested over an alleged fight in a London nightclub.
The 30-year-old was arrested on suspicion of causing actual bodily harm after a man in his 20s was taken to hospital with facial injuries, police confirmed.
It is understood the London-born player, who started his career at Arsenal, was arrested outside the nightclub in Kingly Street around 2.30am on Sunday.
Stack was questioned at a central London police station after a fight broke out inside the venue.
Officers said he was bailed pending further enquiries.
His arrest came just hours after Hibernian suffered their fourth defeat in six games with a 1-0 home loss against Dunfermline.
The Edinburgh club has refused to comment.
