A "VILE" paedophile who sexually abused five girls by playing sick games of chance with them has been jailed for 16 years. Derek Evans, 70, forced his young victims to draw pieces of paper out of a hat and to take part in his own perverted version of postman's knock to decide what form of sex assaults they would suffer. Evans, of Ranelagh Avenue, Ravenscliffe , Bradford, groomed the children with sweets, cigarettes and cider and brainwashed them into thinking they would not be believed if they told anyone. He tried to rape one girl and abused his victims in front of one another, Bradford Crown Court heard. They included one attempted rape, seven charges of indecent assault and five counts of indecency with a child.
