hereThe post, on the Greater Manchester Police Trafford South page, said: "A number of reports have been made of a large gathering of youths (girls & boys) on Weathercock Farm playing fields, off Firs Road, Sale."On police arrival a number of youths run away."Information passed was that it was a planned fight with a number of spectators."Can I ask you make contact with your child and make sure they are not in a large gathering, to prevent any further incidents which may involve your child being
