The Stockholm suicide bomber recorded a shocking audio message in which he warned "our actions will speak for themselves".

Speaking with an English accent, the man can be heard warning that an "Islamic state" has been created and many will die.

The sinister voice is believed to be Taimour Abdulwahab al-Abdaly, who disappeared from his family home in Luton around two weeks ago.

The Iraqi-born Swede is at the centre of an international counter-terrorism inquiry involving police and security services in Britain and Sweden. Investigators are focusing on how al-Abdaly was radicalised from an apparently happy family man to a suspected murderous fanatic.

His beauty stylist wife and three young children were bundled out of his rented three-bedroom family home in Luton by police in the early hours today.

Officers from the Met's Counter Terrorism Command have been scouring the Argyll Avenue home for clues after executing a search warrant on Sunday night. Police are also examining his studies at the University of Bedfordshire and an apparent clash with members of a mosque in the town.

Qadeer Baksh, chairman of the Luton Islamic Centre said al-Abdaly "stormed out" of the Luton mosque he attended after he was challenged over "alien" and "extremist" views.

"I confronted him in front of the whole community and I brought up every single one of the doubts that he had been spreading and that he was debating with me. I dissected his view, refuted with theological arguments that are correct from the Koran.

"He took a dislike to that. He got very upset. He just got up and he stormed out and we never heard from him again after that."

The audio message was sent in an email to the security police and Swedish news agency TT shortly before two bombs exploded in Stockholm on Saturday. The terrorist attacked Sweden's support for the war in Afghanistan and an image by a Swedish artist who depicted the Prophet Mohammed as a dog.
