Detectives investigating after a man was attacked in Oldham town centre have issued a fresh appeal for witnesses.
Thomas Hickey was stabbed repeatedly in the head outside Liquid and Envy nightclub on Waterloo Street in the early hours of March 24 last year.
It's understood he had just left the venue on Retiro Street when he was punched in the face.
Thomas, now 22, tried to run away from his attackers, but the gang chased him down an alley.

He fell over - shattering his knee in several places - and while he was on the floor a gang of men continued to assault him.
Thomas was stabbed twice in the head and also had puncture wounds to his back.

He needed surgery and spent almost two months in hospital recovering.
His dad Martin released images of his injuries, saying his son was ‘lucky to be alive’ after the attack.

Now one year on, GMP is re-appealing for witnesses and are urging anyone who may be able to help identify the people responsible to get in touch.
Det Insp Joseph Harrop said: "This weekend marks the anniversary of this brutal attack and we hope it may prompt someone to remember something.
"Perhaps witnesses who were reluctant to come forward a year ago, for whatever reason, will now feel able to do so.

"Thomas was the victim of an extremely nasty attack and the person – or persons – who inflicted his wounds clearly intended to cause great harm.
"We're appealing to anyone who can help to bring those responsible for this cruel attack to come forward and help with our investigation."
He added: "In addition to releasing CCTV we have made repeated public appeals for information from anyone who was in Oldham town centre in the early hours of 24 March last year.

"Thomas Hickey was attacked at around 2.30am outside the Liquid Envy nightclub and we are convinced someone can identify the people we need to speak to and help to bring justice for Thomas and his family."
Anyone with information is asked to contact the police on 0161 856 5887 quoting reference number 280 of March 24, 2018, or the independent charity Crimestoppers, anonymously, on 0800 555 111.
