World welterweight title contender Amir Khan of Britain will face no further action after being involved in an incident with two youths last week.
"No further action will be taken against a 27-year-old man, who was arrested on suspicion of assault, following reports of an assault on Russell Street in Bolton on Friday 4 July," Greater Manchester Police said in a statement on Monday.
Khan was released on bail after being arrested in the early hours of Friday morning.
He is hoping to challenge Floyd Mayweather Jr for the unbeaten American's World Boxing Association and World Boxing Council titles.
Mayweather beat Argentine Marcos Maidana on points in a title fight in Las Vegas in May and on the undercard of the same bill Khan outpointed American Luis Collazo.
