UK intelligence agency MI5 is paying Muslim informants for controversial short-term spying missions targeting homegrown Islamist extremists.
Individuals across Britain, including in Manchester and London, are being employed on temporary assignments to acquire intelligence, according to sources within the Muslim community.
One said they knew of an informant recently paid 2000 ($4900) by the security services to spy on activities relating to a mosque over six weeks.
However, the use of payments to gather intelligence prompted warnings the system risked producing information "corrupted" by the money on offer.
The initiative is being co-ordinated under the British Government's post-9/11 counter-terrorism strategy, specifically the strand known as Pursue, which has an official remit to "stop terrorist attacks in this country and against our interest overseas. This means detecting and investigating threats at the earliest possible stage".
