UK counter terrorism officers have arrested five men near Sellafield nuclear plant.
The men, all aged in their 20s, were filming when stopped by Civil Nuclear Constabulary officers. They are all Bangladeshi and were travelling in one vehicle.
They were detained under section 41 of the Terrorism Act after a routine vehicle check close to the west Cumbria facility yesterday. All five men are believed to have been living in London.
A Cumbria Police spokesman said: "At 4.32pm yesterday, Monday 2 May, police officers from the Civil Nuclear Constabulary conducted a stop check on a vehicle close to the Sellafield site in West Cumbria.
"As a result, police officers from Cumbria Constabulary arrested five men from London, all aged in their 20s, under section 41 of the Terrorism Act.
"They were taken to police custody in Carlisle overnight and are being transported to Manchester this morning. The investigation is being led by the North West Counter Terrorism Unit."
A road closure affected the area for a short period of time.
