Excerpt:
A man described as a suspected terrorist sympathiser closely linked to the July 7 bombers has worked for Scotland Yard and a string of councils to run training courses about "engaging" Muslim youths.
Tafazal Mohammad was described as an "individual of interest" by MI5 in 2001 when he attended a training camp with the bombings' ringleader, Mohammed Sidique Khan.
Despite a host of links with the suicide attackers, Mohammad now promotes himself as a "professionally qualified youth and community worker" and has been paid thousands of pounds by organisations including the Metropolitan Police and Chester University.
