Agents, including the FBI and bomb disposal officers, swooped on an apartment in the suburbs of the city after a man, said to be of Saudi origin, was arrested at the scene..
The 20-year-old suspect is under police guard in hospital, where he is being treated for burns and shrapnel wounds to his legs, after he was tackled to the ground by a civilian who believed he was acting suspiciously.
It was also reported that he may have had a foreign accent. He is in the country legally on a student visa and is said to be cooperating fully with police inquiries.
He said he had been at dinner with friends the night before and was at the marathon simply because he ‘wanted to see the end of the race’.
He has a clean record, and suffered burn injuries during the explosion.
In an interview with the Boston Globe this morning, his roommate said he highly doubts his ‘clean and quiet’ friend had anything to do with the attack.
