Two of the men arrested in connection with car bomb attacks in London and Glasgow had links to a hospital in Cambridge, it has been reported.
Dr Mohammed Asha, 26, who was arrested with his wife on the M6 motorway, worked on placement at Addenbrooke's Hospital in the city.
A second suspect, Dr Bilal Abdullah, who has been named as one of two men who drove a flaming Jeep loaded with gas canisters into the arrivals hall at Glasgow Airport, also lived in the city and worked at the hospital on placement, it was reported.
Dr Abdullah, who trained as a doctor in Iraq, stayed in Cambridge for short periods in 2001 and 2004.
Electoral records show that he stayed at the home of a kebab shop owner, according to the Times.
A neighbour told the paper that the family were hardline Muslims who worshipped in a prayer room above the shop rather than the local mosque.
In 2001, when Dr Abdullah first lived in the city, he rented a room in a house owned by the Cambridge Muslim Welfare Society, a community group operating out of a local mosque.
Addenbrooke's said it would make no comment on reports that the two doctors had been employed at the hospital.
It issued a statement saying it would co-operate with investigators.
"This matter of national security is under police investigation," said a spokeswoman. "As such we are not in a position to comment."
