A £100,000 reward has been offered to help solve the mystery of missing student Jack O'Sullivan, who vanished 18 months ago after leaving a party.
Jack, who would now be 24, has not been since March 2 last year when he attended a house in Bristol with some friends, but never came home.
Multiple searches and a high-profile campaign has failed to produce a single lead - with his desperate family saying they are 'no closer' to finding out what happened to him since the day he disappeared.
His phone's last known activity was after 6am in the vicinity of Cumberland Basin and Hotwells, and there has been no activity on his bank account since.
Now his mother, Catherine O'Sullivan, has revealed an anonymous benefactor has contacted them to offer the six-figure reward.
