They were found guilty of 16 offences started in May 2011 when the girl was 13 and continued until June 2012. Judge Roger Thomas QC handed the men sentences of between three-and-a-half and 20 years detention, including an extended sentence for Mahmood.
He said: ‘You’re all to be sentenced, all of you, for offences against a young vulnerable child.
‘She was only 13 or 14 when the 12 of you took such terrible and heartless sexual advantage of her.’
The judge said cases such as these were classed as child sexual exploitation
A trial last year heard how the teenager was repeatedly raped by the men in encounters arranged by a violent drug dealer over a period of 13 months between 2011 and 2012.
On one occasion, the girl was gang-raped by five of the defendants.
