Three teenagers were left in hospital following an attack by an armed group of youths in Wythenshawe.
Shortly after 7.35pm on Tuesday 31 October 2017, police were called to reports of a fight at Wythenshawe Metrolink stop.
A group of youths attacked a 17-year-old boy who was left with head injuries.
The group then beat a 14-year-old boy and proceeded to assault a 15-year old boy who was left with head injuries.
All three victims were taken to hospital where they were treated for their injuries.
A 14-year old boy was arrested on suspicion of violent disorder and possession of a firearm with intent to cause fear. He has been released under investigation.
Detective Sergeant Fiona Manning, from GMP’s City of Manchester team, said: “This was a truly horrific and unprovoked attack on innocent boys that were left requiring hospital treatment.
“The boys are understandably extremely shaken by this attack and we are working hard to understand exactly what happened.
“I would like to reassure the community that we have a team of dedicated detectives working hard to identify every person involved and so that we can bring them to justice.
“We will not tolerate innocent members of our community being targeted in such a callous way and you will have seen increased police and TravelSafe patrols in the area following this attack.
“If you witnessed this attack or know anything that could help our investigation, then I would urge you to get in touch with us.”
Anyone with information should call police on 101, quoting incident number 1844 of Tuesday 31 October 2017, or the independent charity Crimestoppers, anonymously on 0800 555 111.
The TravelSafe Partnership, which is led by Transport for Greater Manchester and Greater Manchester Police with support from contributing operators KeolisAmey Metrolink, Stagecoach and First Manchester, aims to deliver a clear message to let communities, commuters and those people committing crime and antisocial behaviour know that we take these types of issues seriously and that we will take action against anyone causing misery across the transport network.
