London - Three men and two women, aged between 16 and 25, have been arrested in Britain under the Terrorism Act, just days before Thursday's summit meeting of Group of 20 (G20) nations, police said Monday.
Police said the arrests were made over the weekend in the port city of Plymouth, south-west Britain, after a man was caught painting graffiti on a wall.
However, police would neither confirm nor deny media reports that the arrests were linked to demonstrations planned in London against the G20 summit later this week.
