Forest Gate source “has IQ of 69”

According to Sunday Mirror.
The former waiter, a childhood friend of the two brothers who were arrested during the raid two weeks ago, was jailed for six years in January for terror offences.
The paper has been told that it was after friends of Mohammed Abdul Kahar, 23, and Abul Koyair, 20, visited the man in top-security Belmarsh prison that the brothers were put under surveillance.
The brothers reportedly laughed off the fact that they were being followed by the security services. New information passed to the services, said to include detailed drawings of a suicide vest, led to Operation Volga and the early morning moves to arrest the pair, the paper claims.
Friends of the brothers told the paper they believe the man was the trigger for the operation that culminated in 250 police officers descending on their home.

So, perhaps the gullibility which commonly affects people with very low intelligence might have been a factor in his being persuaded to tell whatever he told about the brothers that led to the raid? I mean, how can anyone take something such a person says seriously anyway? (More: Osama, Bradford Muslim, Londonist.)
