Nasserdine Menni was arrested by police in Glasgow in March 2011 in connection with a bombing in December the previous year.

The bombing, in which a car blew up in a busy shopping area of the Swedish capital Stockholm, was accompanied by a second explosion.

The authorities in Sweden declared the incidents a "crime of terror" and launched an investigation.

One man who was found dead after the second blast had been carrying an explosive device. Two people were hurt in the attack. Taimour Abdulwahab was named as the dead man. The 28-year-old man - of Iraqi origin - had studied at the University of Befordshire and lived in Luton for a decade.

Mr Menni, an Algerian national, was accused of being part of a terrorist conspiracy along with Abdulwahab. He was also accused of acting with him to further terrorist aims by criminal and other means including the use of explosive devices.

This offence was alleged to have been committed between January 1, 2003 and March 8, 2011 at addresses in Glasgow, England, Sweden, Syria, and Iraq. It was alleged that Abdulwahab detonated an improvised explosive device all with intent to murder members of the public.

The charge against Mr Menni had various claims including an accusation that he repeatedly communicated with Abdulwahab to discuss means by which to pursue the conspiracy. Mr Menni was also said to have transferred money to an account in the name of Taimour Abdulwahab.

Fraudulent claims

After living in Luton, Bedfordshire, for about four years, Menni moved to Glasgow in 2009 as a bogus asylum seeker, claiming he was escaping persecution in Kuwait.

Menni was in fact an Algerian national, but used such a plausible Kuwaiti accent that people from the country who knew him actually believed he was from there.

He managed to fraudulently obtain more than £20,000 in housing and council tax benefits, jobseeker's allowance and financial support.

He was snared when police found a phone on Abdulwahab, which had made calls to a mobile phone in Glasgow on the day of the explosion, December 11 2010, at 2.33pm and 2.36pm.

They placed Menni under constant surveillance for three months, watching him come and go from an asylum seekers' hostel in Curle Street, in the Whiteinch area of the city, where he had been residing.

Bank account activity showed that his transfers to Abdulwahab, which totalled £5725, were always made in cash, as Menni would withdraw money and later deposit it into the bomber's account rather than use direct debits or standing orders.

Arrest

Police arrested Menni on February 7 2011. He was questioned by detectives for five days, answering every one with "no comment".

At his arrest, he told officers he did not know how he could be linked to Abdulwahab, but told a member of the public several months before that he knew a terrorist.

The investigation was supported by the FBI, as well as the Metropolitan Police's anti-terrorism branch and police in Sweden and France.

Investigators still do not know for sure what Menni's date of birth is, but they believe him to be around 31 or 32 years old.

In Glasgow, he worked in various bars and restaurants, including Balthassar on Ingram Street and Mercado, Bell Street, as a glass collector, waiter and a chef.

He also carried out voluntary work with the charity Sense Scotland, organising activities for young people with special needs. Before that, he held down a steady job in Luton with Magna Seating, a car seat manufacturer.

Detectives believe he joined the asylum programme to get away from Luton, putting some distance between his association with Abulwahab in the hope it would keep police off his scent.

He always checked his emails on other people's computers and a search of his residence found no laptop or computer.

Despite having a number of aliases, police now believe his name is Nasserdine Menni, which has been established through his family connections.

He is not believed to have a wife or children. His parents live in Algeria and his brothers, Omar and Ahmed, live in Luton and France respectively.
