Leading jockeys from the world of racing have led tributes to two of the sport's future stars who died in an apparent arson attack. Jamie Kyne, 18, and 19-year-old Jan Wilson perished in the blaze yesterday in Norton, near Malton in North Yorkshire. They were having a party at the time. A local man in his 30s was arrested and questioned by detectives and has been released on bail. Leading jockey Kieren Fallon spoke of his sadness at the teenagers' deaths: "It is very sad and my hearts go out to the family, friends and relatives of the poor kids.It is something you don't like to see in racing or in any other sport." The family of Mr Kyne, from Ireland, who had been booked to ride at Haydock on Saturday afternoon, said they were distraught. His aunt said: "The family are devastated. Jamie was a star." Of his parents, she added: "They are so proud of him. At the moment they are just devastated and shocked." Miss Wilson had been due to ride Imperial Sword, owned by her mother Margaret, at Thirsk. The horse was declared a non-runner on Saturday morning. Mrs Wilson, of Greenhead Farm, Rescobie, said of reports her daughter had been a victim of the blaze: "It hasn't been confirmed. We are waiting to find out." Mr Kyne's friend and fellow apprentice jockey, Ian Brennan was also in the third-floor flat and jumped to safety when the fire ripped through the building at 2.15am. The 20-year-old was released from hospital in the early hours of the morning and went on to ride at Thirsk. A fourth person in the block - believed to be an apprentice jockey - was also taken to York District Hospital and treated for burns and smoke inhalation.
