[3] Storm visited the Regent's Park Mosque in London and was offered a scholarship to study Arabic and Islam at a religious, Salafi school in Yemen.
He then moved to Brixton, where he met Zacarias Moussaoui (the "wannabe" 9/11 hijacker) and "Shoe-bomber" Richard Reid.
The Guardian reported that while in London, "Storm and his associates inhabited a world of overstayed visas, violent online videos, idolized preachers, frustration and alienation.".
[3] Storm and the Islamic radicals he lived with were amateurish but threatening and connected to a global network of contacts who shared ideology and purpose.
In London Storm became friends with Anwar al-Awlaqi, an American-born Yemeni, who at one time was regarded second only to Osama bin Laden in the Al-Qaeda network.
In the past, Storm had been contacted by MI5 and PET (Politiets Efterretningstjeneste, or Danish Security and Intelligence Service), but he had refused their offers of collaboration.
However, in 2006, as he became increasingly dissatisfied with militant Islam, Storm contacted the European domestic intelligence agencies.
According to Storm, a Croatian woman was selected and given a tracking device to carry in her suitcase, which would reveal al-Awlaki’s residence on her arrival there.
In August 2012, PET offered Storm DKK 25,000 per month tax-free for five years in return for his silence.
They wrote, in part:[5] Normalt udtaler vi os jo ikke om målene for vores operative arbejde.
Det kommer dog næppe bag på nogen, at PET som andre vestlige efterretningstjenester har haft fokus på al-Awlaki, og at PET's operative indsats i forhold til al-Awlaki har været rettet mod at afdække konkrete terrortrusler mod Danmark eller danske interesser i udlandet, herunder eventuel kontakt mellem al-Awlaki og terrorrelaterede personer, grupper eller netværk i Danmark.
At a July 2014 political event on Bornholm, Storm participated in a debate arranged by the International Free Press Society.
