Police were on Thursday granted more time to question the 30-year-old man of Kuwaiti origin over his suspected links to the attack which killed the suicide bomber, Taimour Abdulwahab, and injured two others in the Swedish capital.
The man was arrested in a pre-dawn raid in the Whiteich area of Glasgow on Tuesday and is being held at Govan police station.
His identity remains unconfirmed with reports suggesting that he was nursing student at North Glasgow College rejected by the college, the newspaper reported.
The Swedish Security Service and the UK's MI5 are reported to be assisting the police with their enquiries. According to UK anti-terror laws the police are able to detain the man for questioning without charge for 14 days.
Taimour Abdulwahab, a Swedish citizen who lived in the British town of Luton with his wife and three children, narrowly missed wreaking carnage among Christmas shoppers when he blew himself up next to Stockholm's busiest pedestrian street on December 11th.
He was carrying a cocktail of explosives and is believed to have mistakenly set off a small explosion that killed him before he could carry out what appears to have been a mission to kill "as many people as possible," a Swedish prosecutor said days after the attack.
An Islamist website, Shumukh al-Islam, posted a purported will by Abdulwahab which said he was fulfilling a threat by Al-Qaeda in Iraq to attack Sweden.
Shortly before the explosions, Säpo and the TT news agency received an email with audio files in which Abdulwahab is heard telling "all hidden mujahedeen in Europe, and especially in Sweden, it is now the time to fight back."
The attack was the first suicide bombing on Swedish soil.
