Terror suspects escape authorities
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.
It was understood the man, who has not been named, escaped from a mental health unit and has been on the run for two weeks.
The man, a British citizen, was believed to have climbed through a window to evade staff at the London unit.
Control orders act as a loose form of house arrest, and usually place suspects under a curfew and require them to report regularly to police.
The man now on the run may have been suspected of playing a role in international terrorism, possibly linked to al Qaida groups. It is understood that he was placed on a control order in early April.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.''
In the other incident, believed to have taken place some months ago, the suspect is also still at large.
Control orders were brought in at the beginning of last year as a replacement for indefinite detention without trial or charge.
The identities of people on control orders are not revealed by the Home Office.
Liberal Democrat home affairs spokesman Nick Clegg said: "Since control orders were the Government's flagship anti-terrorism measure, this is a huge embarrassment for them."As we have always made clear, the danger of control orders is that they short-circuit due process and keep suspects in a state of limbo."
