A man who died in one of two explosions in the Swedish capital had explosives strapped to his body and in his backpack, and had sent threats referring to "jihad" in an email shortly before his death, a prosecutor said on Monday.
Tomas Lindstrand said the police are "98 per cent" certain the suicide bomber was a 28-year-old Swedish citizen, Taimour Abdulwahab, who also lived several years in Britain.
Abdulwahab had his roots in the West Asia and had been a Swedish citizen since 1992. He was the registered owner of the car that exploded in Stockholm shortly before the suicide blast Saturday that also wounded two people.
He said the e-mail threats that were sent to security the police and Swedish news agency TT before the blasts have been linked to Abdulwahab's cellphone.
Abdulwahab had explosives strapped to his body and in a backpack, Lindstrand said. He also said he carried "something that looked like a pressure-cooker."
A Facebook account that appeared to belong to Abdulwahab showed he previously studied at the university of Bedfordshire in Luton. On Sunday, British police raided a property in Bedfordshire, but didn't make any arrests.
On his account he also posted comments against Shias, whom Sunni Muslims consider heretics.
He also posted a link to a video showing a dying man, maybe injured in Chechnya, praying to God to die as martyr.
Abdulwahab commented on the video, writing: "Taimour likes Abu Dujana, the death of a shagged (martyr)."
The audio file sent in an email to the security police and Swedish news agency TT shortly before the blast referred to jihad, Sweden's military presence in Afghanistan and an image by a Swedish artist that depicted the Prophet Mohammad as a dog, enraging many Muslims.
Because of the country's silence toward all this, "so will your children, daughters, brothers and sisters die, like our brothers, sister and children die," a man's voice said in the file, submitted to the Associated Press by TT.
"Now the Islamic state has been created. We now exist here in Europe and in Sweden. We are a reality," he said. "I don't want to say more about this. Our actions will speak for themselves."
