A teenager was stabbed by a gang of seven men who then turned on his friend and tried to knife him too.
The gang of six or seven men reportedly approached the teenager and knifed him in his thigh.
Another member of the gang then attempted to stab a friend of the victim and then made off towards Gaskell Park, in the direction of Havana Flash.
The teenage victim was taken to hospital for treatment with what was described as a non-life threatening injury.
Earlier today, officers arrested a 17-year-old man, from the Newton area in connection with the attack.
CCTV, forensic and witness enquiries are continuing, with detectives wanting to hear from anyone with information.
Detective Inspector Tony O’Brien said: “We will not tolerate knife crime in our community and this attack is completely unacceptable.
“We urgently need to hear from anyone who was in the area and saw or has since heard anything. Thankfully the victim was not more seriously injured, but this was a frightening incident for the victim and his friend.
