After converting to Islam, a former member of a Danish motorcycle gang travels to Yemen to study the Quran and soon comes in contact with radical preachers waging holy war against the West.On the verge of becoming a jihadist, he abruptly abandons his faith and embarks on a dangerous undercover mission to help Western intelligence agencies capture or kill terrorists.Morten Storm's unlikely story, told in a new book and an interview with The Associated Press, has the drama and intrigue of an episode of the "Homeland" TV series. But the burly, red-bearded Dane insists his tale isn't fiction.Storm, 37, claims he worked for six years as an informant for the CIA, Britain's MI5 and MI6 and Denmark's security service, PET. All declined to comment for this article."Could they just say 'he never worked for us'? Sometimes silence is also information," Storm told the AP in Copenhagen. "I know this is true, I know what I have done."The book , "Storm, the Danish agent in al-Qaida,"is set for release Monday in Denmark, but Storm gave the AP an advance copyStorm said he decided to reveal his secret-agent life to the media - he first spoke to a Danish newspaper in October - because he felt betrayed by his agent runners.In particular, he was upset that he wasn't given credit for the airstrike that killed Anwar al-Awlaki, a senior al-Qaida figure, in Yemen in 2011.Storm claims the CIA won't admit that his work helped them track down the U.S.-born cleric, who has been linked to the Fort Hood, Texas, shootings and the attempted Christmas Day bombing of a jetliner approaching Detroit in 2009.Storm also claims to have played a role in a series of well-documented anti-terror operations in the past six years by infiltrating extremist mosques in Britain and militant groups in Somalia. He often met his handlers in exotic locations and provided a photograph of one such rendezvous with purported PET agents, at a geothermal spa in Iceland.Another photograph shows a suitcase packed with cash - $250,000 he claims to have received from the CIA for an undercover operation to track down al-Awlaki though that effort ultimately failed.Bob Ayers, a former U.S. intelligence officer, cast doubt on Storm's claims."Just because he claims to have worked for these agencies doesn't mean he was on anyone's payroll as he almost certainly would not get clearance," said Ayers, who now lives in London."It is also doubtful that he would have been one of Awlaki's trusted insiders. The only thing less trustworthy than an enemy agent is an enemy agent who has turned."A European security official not affiliated with any of the four agencies Storm claims to have worked for said he may well have been an informer, but questioned the way Storm described his own significance."I have a strong feeling that he's overestimating his own role," said the official, who spoke on condition of anonymity because he was not authorized to discuss the matter publicly.Storm says he provided information that led to the 2007 arrest in Britain of Hassan Tabbak, a Syrian-born man sentenced to seven years in prison for trying to make bombs in preparation for terrorist attacks.In his book, Storm also says he was involved in an operation targeting Saleh Nabhan, a senior al-Qaida operative killed by Navy SEALs in a helicopter attack inside Somalia in 2010.The most elaborate operation involved al-Awlaki. In 2009, Storm said, he helped the reclusive cleric in his efforts to find a European wife, pairing him up with a Muslim convert from Croatia named Aminah. Storm said he helped carry encrypted video messages between the soon-to-be spouses on a flash drive, before they decided to meet in Yemen. He provided those video clips to AP.A tracking device was placed in Aminah's suitcase, but the plan failed when she was told to transfer her belongings to a plastic bag upon arrival in Yemen, Storm said.However, Storm was sent back to Yemen, supplying various items through a courier to al-Awlaki, who still didn't suspect he was being double-crossed. The Dane believes his work eventually helped the CIA pinpoint al-Awlaki's position.The Americans "had to crawl back to the Danish intelligence to beg them if I would travel back to Yemen and try to recreate or reestablish the contact, the communication with Anwar," Storm said. "Within four weeks, the contact was up again."Storm, who hails from Korsoer, 75 miles (120 kilometers) southwest of Copenhagen, has past convictions for bar fights, violence, cigarette smuggling and petty theft stretching back to his early teens. He was a prospective member of the Bandidos biker gang before a Muslim jailmate convinced him to convert to Islam in 1997.Storm later spent time with radical Islamists in Britain and Yemen, married a woman from Morocco and named their first son Osama after al-Qaida leader Osama bin-Laden.He wanted to join Islamist militants fighting in Somalia in 2006 but they rebuffed him. Storm said his anger at that rejection turned to doubts about his religion. Soon he had a complete change of heart, and offered his services to PET agents, who put him in touch with their U.S. and British counterparts.Storm said his relations with the CIA turned sour after he was told that al-Awlaki was killed in a separate operation. In a meeting at a seaside hotel in Denmark, he secretly recorded a conversation about the issue with a man he claims is a CIA officer.The man, known to Storm as Michael, thanked him for his efforts but added that "there were a number of other projects" to track down al-Awlaki. Michael said it was like in a soccer game when several players are in a position to a score."The other guy could pass it to you, but he didn't. He took the shot, he scores," Michael said."That's what happened."Storm wasn't satisfied with that explanation.After spilling his secrets, Storm says he believes he's now become a potential target not only for al-Qaida, but the CIA.

"I think that when a person potentially could become a liability, it is what easiest for intelligence services to get rid of their agents and especially people like me," Storm told the AP.He offered no firm evidence to suggest the CIA, or any other agency, had plans to hurt him.
