LONDON — British police said Tuesday they had arrested a 30-year-old foreign national in Scotland in connection with a suicide bombing in Stockholm in December.

The man was detained in a dawn raid in Glasgow on suspicion of "aiding terrorist activities" abroad, police said. Officers were also thought to be searching two other addresses in the city.

British authorities had been investigating any links to the Swedish attack -- the country's first suicide bombing -- following the revelation that the bomber, Taymour Abdelwahab, had lived and studied near London.

"At 06:05 am (0605 GMT) on Tuesday, March 8th, Strathclyde Police conducted an operation in the Whiteinch area of Glasgow," a police statement said.

"This has resulted in a 30-year-old foreign national being arrested under the Terrorism Act. The operation centres on a previous incident in Sweden.

"It was intelligence-led and relates to allegations that this individual has been involved in aiding terrorist activities outside Scotland."

The statement added that there was "no evidence" to suggest the arrested man posed any direct threat to Scotland.

On December 11, Abdelwahab, a 29-year-old whose family fled from Iraq to Sweden in 1991, blew up himself and his car in an empty side-street off of Stockholm's busiest pedestrian thoroughfare, injuring two people.

Before the attack, he had lived in Luton, north of London. He had graduated with a degree in sports therapy from the city's university seven years earlier.

The connection sparked fresh soul-searching in Britain about how to combat radicalism, five years on from the attacks on the London transport system in 2005, which left 52 people plus the four bombers dead.
