Up to 70,000 people are being invited to help find missing Stone Roses fan Christopher Brahney during an event on Piccadilly Gardens, Manchester, tonight.
The 22-year-old has been missing since Friday after going with friends to the Madchester band’s gig at Heaton Park.
Since his disappearance, a Facebook group has been set up to help find Mr Brahney – and more than 74,000 people have joined.
Event organiser Laura Roberts said: “We want everyone in Manchester to know about this and it would nice to speak to people in person, who might know anything.”
Flyers and posters are being handed out in order to find the young man as concerns for his whereabouts continue to grow.
Yesterday The Stone Roses issued a plea for the public to help the search for Mr Brahney.
“If you saw Christopher at the end of the evening please get in touch with Greater Manchester Police and spread the word to everyone who came to the show.
“Our thoughts are with Christopher’s family and we all want to see him back at home safe and sound.”
Mr Brahney is white of slim build, with short brown hair.
He was last seen wearing a dark blue top, light blue shirt, maroon trousers and green wellington boots.
Detective Chief Inspector Melani Linton said: “Christopher’s family are clearly very worried about him and are desperate for any information relating to his whereabouts.
“We believe Chris may have used the park and ride facility at Bowlee Park, Heywood Old Road, Middleton. There were dozens of coaches in the car park with destinations all over the country.
“Chris could have got on one of these coaches, did you see him or speak to him?
“I would urge anyone with any information to contact the police, this could be vital to our investigation and provide some much needed answers for his family
“Christopher, if you see or hear this appeal, we would ask that you make contact with us or your family as soon as possible.”
Anyone with information is asked to call police on 0161 856 7652.
