Two suspected international terrorists are on the run after going Awol on control orders.
In the latest incident, a man who escaped from a mental health unit has been on the run for two weeks. He is believed to be a 25-year-old British man.
In the other incident, believed to have taken place some months ago, the suspect is also still at large.
The Home Office has not made public any details about the escapes.
Both men now on the run will have been suspected of playing a role in international terrorism, possibly linked to al Qaida groups.
The most recent incident is believed to involve a man who appeared at the Old Bailey earlier this year.
He was believed to have climbed through a window to evade staff at a psychiatric unit at Middlesex University Hospital at Isleworth, south-west London.
It was thought he was handed his control order on April 5.
His admission to the mental health unit was thought to have been a more recent development and would not normally have been part of the control order conditions.
A Home Office spokeswoman said: "Any breach of security will be investigated on a case-by-case basis. We do not discuss individual cases."
