British police say five men have been arrested under anti-terrorism laws after being near a nuclear power plant in northwest England.
Cumbria Constabulary said the men were detained under the Terrorism Act near the Sellafield plant on Monday after officers stopped a car. All are from London and in their 20s. They were being held Tuesday at a police station in Manchester.
Prime Minister David Cameron has said Britain should be extra-vigilant against terrorism in the coming weeks following the death of Osama bin Laden.
