One of the men being held in connection with the failed attack on Glasgow airport studied in Belfast.
A burning jeep was rammed into Glasgow airport
Kafeel Ahmed, who is in hospital with severe burns, was one of two men arrested when a burning jeep was rammed into Glasgow airport.
It has emerged he was an aeronautical engineering student at Queen's University in Belfast.
A spokeswoman for Queen's said Scotland Yard had advised that they say nothing in relation to Mr Ahmed.
It is believed he enrolled for a post-graduate course at Queen's in 2001 and then stayed on as a research assistant until the middle of 2004.
It is understood that he is currently too ill to be questioned by police about the attack.
Mr Ahmed has been transferred from the Royal Alexandra Hospital in Paisley to a specialist burns unit at Glasgow Royal Infirmary, where he is under armed guard, health officials said.
The suspect studied at Queen's University
Jamal Iweida of the Belfast Islamic Centre said he knew Kafeel Ahmed and was shocked at what had happened.
"I knew Kafeel for about two years while he was staying in Belfast as a postgraduate student at Queen's University," he said.
"My memories of Kafeel are of a very pleasant and calm person, a very intellectual person, very friendly and sociable in fact."
Eight people have so far been arrested in connection with last week's attacks in London and Glasgow.
