The parents of tragic Bradford teenager Adam Dixon have paid tribute to their “wonderful” son.

Adam, 18, of Shelf, was found dead at his halls of residence in Leeds at the weekend. Toxicology tests are taking place to establish the cause of death, but it is understood he had taken Ecstasy.

A 22-year-old man from Leeds, who was being questioned by police after he was arrested on suspicion of supplying controlled drugs, was yesterday released on bail pending further inquiries.

Yesterday, Adam’s parents, Tracey and Dave, released a new photo of their son and a statement.

It read: “Adam was a wonderful son and brother, of whom we were extremely proud. He touched the lives of all the people he met.

“We are absolutely devastated by our tragic loss, and would ask that we be left to grieve in peace at this extremely sad time.”

Friends also paid fresh tribute to the former Hipperholme and Lightcliffe High School pupil, who was in his first year studying multimedia technology at Leeds Metropolitan University.

School pal Tom Lamb, 19, spoke of the “quiet” teenager who was good at rugby.

He said: “We used to get the bus home together. I never knew him to be a big drinker and am really shocked. I had heard that he died in his sleep.

“He didn’t have any enemies. He wasn’t the sort of guy to take drugs.

“He was into his music and no-one ever had a bad word to say about him.”
