Glen Jenvey began studying radical Islamic groups when he was in college. His first job as a spy, was for the United States authorities to spy in Iran. He was hired by the Sri Lankan National Intelligence Bureau in London to spy on the Tamil Tigers' offices and demonstrations in London. Over the years, Jenvey has worked for the intelligence services of several other countries, including Sri Lanka and India with close links to Russia and USA. He infiltrated the 'Tamil Tigers,' a group credited with the first suicide bombings.
Jenvey eventually began using the internet to infiltrate terrorist organizations. It was through his online work that he developed a relationship, and subsequently helped bring down, Abu Hamza al-Masri by providing film footage of James Ujaama. This led to a New York court case against Hamza and his arrest in London. Hamza was a leading cleric at Finsbury Park mosque in London.
Glen Jenvey worked for several military attachés covering terrorist groups, including al-Qaida and their members in Britain. His sting led to the capture of Abu Hamza al-Masri, a major terrorist. Multiple other terrorists were also caught due to his efforts. He has been profiled and interviewed in major media across the globe, including in the US, UK, Russia, India, etc. He co-authored the book "War of the Web" with Jeremy Reynalds.
