London ( CNN ) -- Veteran cagefighter Usman Raja has so far worked to deradicalize 10 convicted terrorists after they completed their prison terms in the UK . His work combines teaching Mixed Martial Arts skills and a humanistic and tolerant interpretation of Islam that traces its roots back to the Prophet Mohammed . His success has been noted by British officials who are trying to work out if it can be replicated on a larger scale . Read how Raja 's controversial technique works , is changing lives , and getting noticed . Here are some of his cases : . Abu Bakr Mansha , a British-Pakistani , who is now 28 , was in 2005 convicted of terrorism in what prosecutors alleged was a thwarted plot he embarked on that year to track down and kill or severely harm a British soldier who had returned from Iraq . He had pleaded not guilty to a charge of possessing information likely to be useful to a person committing or preparing an act of terrorism . Mansha was released in 2009 under strict conditions but recalled to prison several months later because he was assessed as still dangerous . After he was again released in March 2011 , he entrusted himself to Raja , under whose mentorship he appears to have shed his radical views . Mansha 's police mug shot was used in British newspaper stories warning of a threat from released terrorist convicts to the Olympic Games . He says he now wants to stop other young Muslims from repeating his mistakes . `` I learned the hard way , '' he told CNN . Raja said his first terrorist case was Yassin Nassari , now 33 , a British-Syrian resident of London , who was arrested by police after he landed in Luton airport in 2006 after a trip overseas . Police say they found instructions on how to make a viable rocket on his hard-drive , and at his home violent videos of terrorist attacks and beheadings . The following year Nassari was found guilty of possessing information likely to be useful to a person committing or preparing an act of terrorism . According to Raja , when he was released in 2008 , Nassari was very reluctant to work with Muslim community groups enlisted by probation services to rehabilitate offenders . But Nassari heard about Raja through friends who had trained with him in mixed martial arts and agreed to meet him . In the early summer of 2009 they met in a probation office in London and from there Nassari wanted to work with Raja . He said Nassari was interested in getting mixed martial arts training , and the instruction he gave him in cage fighting allowed him to build up a mentoring relationship . The two had wide-ranging discussions about Islam , during which time Raja was able to impress upon Nassari his humanistic approach to the religion . `` What I think he recognized was our sincerity - that we were doing this for the infinite good , '' Raja told CNN . The former convict is now working at a charity providing a support structure for Muslims convicted of criminal offenses after their release from prison , according to Raja . Andrew Rowe . Raja described how another one of his early success stories was Andrew Rowe , a radicalized British-Jamaican convert who was 34 when convicted in 2005 of terrorism offenses after instructions on how to fire mortars , a coded list of methods of attack , possible targets , and traces of explosive were found on his possessions . Rowe had travelled to several Jihadist fronts , including Bosnia , Chechnya , Pakistan and Afghanistan and was described as `` a global terrorist [ who ] has been trained and knows how to use extreme violence , '' by a senior British counter-terrorism official . Raja says Rowe began training on mixed martial arts whilst in prison . On his release Raja provided him with further martial arts instruction , which helped him forge a mentoring relationship . Raja said Rowe was already looking to improve his religious understanding , making him open to Raja 's message . Other Cases . Raja has also worked with two men convicted of terrorism offenses in relation to the failed July 21 , 2005 bombing attack on London , a man convicted of a terrorist arson attack , as well as several other former terrorist convicts . He is set to take on several more released terrorist convicts in the coming months . CNN 's Ken Shiffman contributed to this report .
