The man believed to be the Stockholm bomber was thrown out of a mosque for preaching about suicide bombings and attempting to recruit extremists, religious leaders have said.
Iraq-born Taimour Abdulwahab al-Abdaly, 28, lived in Britain for almost a decade after leaving his adopted home in Sweden to study and start a family in Luton.
Muslim leaders in the town said he stormed out when they confronted him as he tried to “sow seeds of discord and extremism”.
Farasat Latif, secretary of the Luton Islamic Centre, said the suicide bomber attended for a couple of months in 2006 or 2007.
He described how al-Abdaly was “bubbly” and “well-liked” but harboured increasingly radical and violent views.
Mr Latif said: “It was fed back to the committee of the mosque who explained that his ideas were incorrect. He seemed to accept it. We thought we had led him back to the truth.
“One day during morning prayers in the month of Ramadan – there were about 100 people there – the chairman of the mosque stood up and exposed him, warning against terrorism, suicide bombings and so on.
“He knew it was directed at him. He stormed out of the mosque and was never seen again.”
Two people were wounded in central Stockholm in the first suicide bombing in the history of Sweden on Saturday afternoon.
Prosecutor Tomas Lindstrand said investigators are “98%” certain the suicide bomber was al-Abdaly, who may have died when his bomb went off prematurely.
