Former boxing world champion Amir Khan has been arrested on suspicion of two assaults in Bolton.
Khan, 27, was held after two teenagers were attacked in the early hours of Friday.
A Greater Manchester Police spokesman said: "Just before 1.30am on Friday, police were called following reports of an assault in Bolton.
"Officers attended Russell Street and discovered two 19-year-old men had been assaulted. Their injuries are not serious.
"A 27-year-old man was arrested on suspicion of two section 47 assaults."
The former WBA and IBF light welterweight champion has been released on bail until mid July.
An ambulance spokesman said paramedics attended the scene but those at the scene refused treatment.
A spokesman for the light welterweight fighter confirmed he had been questioned by police but was expecting the case to be dropped.
He added that some reports in the media had seen the allegations "blown out of all proportion".
"It was a minor incident and we're expecting the case to be dropped against Amir," the spokesman said.
"We're expecting to formally hear that from police on Monday morning."
Khan later tweeted about the arrest, writing: "All nonsense please don't believe what you read. I'm home with my family and nobody got beat up."
