A teenage rapist who threatened to stab his "vulnerable" victim has failed to convince judges his eight-year sentence was too tough. Ibrahim Abdulle (19), from Leicester, was with another man wandering around Leicester railway station on October 8 last year when they came across their victim, who is in her mid-40s. She agreed to engage in a sex act with the other man in exchange for £9, Mr Justice Singh told London's Appeal Court. Abdulle was convicted of rape at Leicester Crown Court and jailed for eight years on May 6.
