Another resident who witnessed the scenes said it was 'chaos' - and buses couldn't get through the road for a time because of the amount of people involved.
Officers on Manchester Road could be heard shouting 'off' and 'get off the street' in video footage being circulated on Facebook, as more police and a Tactical Aid Unit van arrived at the scene.
According to unconfirmed reports, a large number of those involved eventually walked off towards Slattocks and Middleton.
One witness said: "I came back from my dad's and saw loads of flashing lights.
"There were up to a hundred kids aged between 15 and 20 and the police were dealing with them."
