British police were today questioning a seventh man in connection with an investigation into an 18-month "Real IRA" bombing campaign in Britain.
The 26-year-old was arrested under the Terrorism Act 2000 last night and is being detained at a West Yorkshire police station, Scotland Yard said this morning.
Police are still searching a disused pig farm at West Ardsley, near Leeds, as part of the anti-terrorism operation.
Officers and an Army bomb squad began searching the farm on Thursday and a series of controlled explosions were carried out.
Six suspected "Real IRA" members are still being held in London.
On Friday magistrates in London granted a three-day extension for officers to continue questioning the six until Monday afternoon.
The suspects, who were arrested early on Thursday, are aged between 20 and 40. One is thought to be from the Republic of Ireland, while the rest are believed to be from England.
Five were arrested at addresses in London and one in Liverpool.
A Metropolitan Police spokesman today said that all suspects would continue to be questioned by detectives in London.
In West Ardsley, about 20 residents in Batley Road had been evacuated from their homes but were all allowed to return home on Friday night after the tight cordon was lifted.
Yesterday, the quiet village road was practically deserted with just six police officers standing guard near the farm.
