Some 800 Muslims lodged in British jails may have been turned by fellow inmates into fanatics ready to launch terror attacks, a media report said on Friday.
An alarming report by defence experts warns that the security services face a "significant challenge" in spotting and keeping tabs on possible suicide bombers and other jihadists as they would be freed from prison over the next five to 10 years, Daily Express reported on its website.
The Royal United Services Institute’s study, released on Friday, predicts a switch from highly-planned outrages such as 9/11 and the London 7/7 bombings to attacks by lone suicide bombers with only slight links to Al Qaeda and using home-made explosives.
The authors warn: "Perhaps some 800 potentially violent radicals, not previously guilty of terrorism charges, will be back in society over the coming five to 10 years."
The report also says that many of those caught in anti-terror campaign of recent years were not convicted of very serious charges and will, therefore, be freed fairly soon.
