Description A former Rotherham taxi driver has been found guilty of raping and sexually assaulting two girls more than 20 years ago. Adam Ali, 43, attacked the girls between 2001 and 2004. Sheffield Crown Court heard he repeatedly assaulted one victim, threatening to leave her stranded if she did not do what he told her. Formerly known as Razwan Razaq, Ali was found guilty of four counts of rape and three of sexual assault after a trial. He is due to be sentenced on 28 July. 'Clear message' Ali was prosecuted as part of Operation Stovewood, the National Crime Agency's investigation into non-familial child sexual abuse and exploitation that took place in Rotherham between 1997 and 2013. Liz Fell, from the Crown Prosecution Service (CPS), praised the victims in the case for coming forward. She said: "It is because of their evidence that we were able to secure a conviction and bring their abuser to justice. "I hope this conviction sends a clear message that the CPS, working alongside law enforcement, will relentlessly pursue justice and prosecute those who sexually exploit children, whenever that abuse takes place." Ali was previously sentenced to 11 years imprisonment in 2010, after being convicted of committing offences of a similar nature.
