The man arrested by detectives investigating an alleged arson attack that killed two promising apprentice jockeys has been released on bail, police said.
The man, who is in his 30s, was held by police probing the blaze that killed Jamie Kyne, 18, and Jan Wilson, 19, at a block of flats in Norton, near Malton, North Yorkshire, in the early hours of Saturday.
A North Yorkshire Police spokeswoman said: "The man who was arrested in connection with the incident has now been released on conditional police bail."
Kyne's friend and fellow apprentice Ian Brennan, 20, was also in the third-floor flat and jumped to safety. He was released from hospital in the early hours and went on to ride at Thirsk.
Dean Pratt, also an apprentice, was taken to York District Hospital and treated for burns and smoke inhalation.
The bodies of the two victims have been removed from the wrecked property and at the scene of the blaze, a number of people came to lay tributes.
Police, who are appealing for anyone who was in the area between 1 and 2am to come forward, had earlier accompanied family members to the scene, though they would not confirm who they were connected to.
Crime scene investigators from North Yorkshire Police, the Forensic Science Services and specialist fire investigation officers were carrying out a full examination to establish the cause of the fire.
"The people who died were found on the second floor of the property. A post-mortem is expected to be carried out in the morning," a police spokeswoman said.
Kyne's parents, Gerry and Madeline, and his four brothers and younger sister are being comforted by relatives. The family run Kiltrogue stud farm in Claregalway, Co Galway. Miss Wilson is thought to have been an only child and her family are from Scotland.
