Earlier this year, an imam working in Stoke-on-Trent was jailed for raping a 12 year old boy at his mosque. In the wake of the case, File on 4 investigates whether the thousands of children who visit mosques and madrassas each week to study the Quran are being properly protected.

The leader of the Muslim Parliament of Great Britain has warned that without urgent action, his religion could face an "avalanche" of historic cases similar to the ones which have swamped the Roman Catholic church. Already, several other abusers whose crimes remained undetected for decades have been brought to court.
