One of the two suspected terrorists, who hacked a British soldier to death on a busy London street, was radicalized in Britain's most notorious youth jail.
Michael Adebowale is believed to have developed his sick views while he was serving a sentence for drug-dealing in Feltham young offender institution.
According to the Mirror, Madeleine Edwards, 49, a friend of the family, recalled how Adebowale had been in some serious gangland trouble and his mother told her he had to disappear for a while.
After converting to Islam she said his attitude had changed.
Adebowale was a member of the notorious Woolwich Boys gang when he was first convicted of selling drugs at the age of 16, the report said.
He was given a community order at Woolwich crown court in 2008, but twice appeared before a judge that same year for breaking bail conditions.
In March 2009 he was back before the same court, where he was jailed for 15 months for possessing heroin with intent to supply.
