UK police arrest teenager on terror offences

British police said yesterday that they had arrested a teenager under terrorism laws following the discovery of a "suspicious item" on a London underground train near the Canary Wharf financial district a day earlier.

Officers discharged a stun gun during the arrest of the 19-year-old in north London who was detained on suspicion of preparing terrorism acts, London's Metropolitan Police (MPS) said in a statement.

"Officers are keeping an open mind regarding any possible motive. They are not looking for anyone else in relation to this investigation at this stage," the statement added.
