Shabir Ahmed, 59, led a child sex exploitation ring of nine men who targeted vulnerable young girls in the Rochdale and Oldham areas of Greater Manchester.
He was jailed for 19 years last month following an 11-week trial at Liverpool Crown Court.
But Ahmed - known to his victims by the nickname "Daddy" - could not be named as he was awaiting trial on separate child rape charges.
Today he was convicted of 30 charges of rape by a jury at Manchester Crown Court and Judge Mushtaq Khokhar lifted reporting restrictions, which means he can be identified for the first time.
The court heard that he raped and sexually abused a young Asian girl over many years.
