A fourth man from the West Midlands has joined three others being held by the US authorities in Cuba.
Moazzam Baig was arrested in Pakistan last February
The Foreign Office has confirmed that father-of-four, Moazzem Begg, was moved from Afghanistan to a holding facility at Guantanamo Bay two weeks ago.
Mr Begg, 30, from Sparkbrook, Birmingham, was arrested in Pakistan last February on suspicion of links with the Taleban regime or the al-Qaeda terrorist network.
He joins three men from Tipton - Shafiq Rasul, 24, Asif Iqbal, 20, and Ruhal Ahmed, also 20.
So far, no charges have been laid against any of the men.
Four visits to base
More than 600 prisoners are being held by the Americans.
In the past year, Foreign Office officials have made four visits to Guantanamo Bay.
They say there has been a significant improvement in the quality of conditions in which the men have been held.
Another visit is scheduled for this week to check on Mr Begg.
