Police today warned of the dangers of binge drinking after a teenager was convicted of carrying out an horrific rape after consuming a litre and a half of vodka. Sean Thomas Regan, 16, pleaded guilty to two counts of rape and one charge of making threats to kill. His victim, a 34-year-old mother of two, was asleep on the sofa at home when Regan broke in. Bradford Crown Court was told Regan's facial demeanour kept changing. He was calm and almost gentle-looking, turning to an expression of hatred as he told his victim what he was going to do to her. During the attack at a flat in Skipton, North Yorkshire, in March this year Regan threatened to rape his victim's daughter. The prosecution said he had admitted drinking a litre and a half of vodka. Today Detective Sergeant Matt Walker of North Yorkshire Police, who was involved in the case, warned of the dangers of binge drinking. He said: ''This was an absolutely appalling incident. An extremely violent incident fuelled by alcohol. ''It highlights the problems with young people drinking excessive amounts of alcohol. ''Hopefully the victim can put the ordeal behind her and rebuild her life.'' Judge Robert Bartfield described the attack as one of the worst he had come across and ordered that Regan, who was 15 at the time of the attack, could be identified despite his age. Sentencing him to seven years in detention on Monday he said: ''I would characterise your behaviour as that of a wild animal. ''This is one of the most disgusting rapes I have ever had to deal with.'' The court heard that Regan was a hardworking student who could be shy at times. His victim fled the flat after the attack and police later found Regan there almost naked and in a drunken stupor. The next day he was interviewed and told officers he had no recollection of the attack, had been very drunk and had blacked out. Regan, of Beanlands Place, Crosshills, near Skipton, was of good character and had no previous convictions, the court heard. He was ordered to sign the sex offenders' register indefinitely.
