LONDON (AP) British police have shut down two tunnels and a bridge at a river crossing on a major highway that serves London following the arrest of a pedestrian and the discovery of an unspecified suspicious item.
Officials say the Dartford Crossing, just east of London, has been closed since roughly 4 p.m. (1500 GMT) Friday after a man was reported "behaving unusually" in the vicinity.
Kent Police, which is responsible for the area, said the man had been arrested and that a "suspicious item" had been recovered from the scene. Police offered no further details.
The Dartford Crossing connects the north and south part of London's M25 ring road.
The crossing handles approximately 140,000 vehicles and the closure has caused huge jams in both directions.
