Seven terror suspects have been released from specialist control measures and there are currently no individuals subject to the controversial powers, the terrorism watchdog has confirmed.

Terrorism Prevention and Investigation Measures (Tpims) expired between January 2 and February 10 for seven out of 10 men, who are all believed to have been involved in al Qaida-related terrorism, David Anderson QC, the independent reviewer of terrorism legislation, said.

This means the suspects, among whom are two men believed to have taken part in the airline liquid bomb plot of 2006, are no longer subject to such restrictions as curfews, exclusion from certain areas and controlled access to computers.

Tpims expire as they have a two-year limit on their use, unlike the terror control orders they replaced in January 2012.

In his report on Tpims in 2013, Mr Anderson calls for constraints on location to be introduced, such as restoring the power to relocate subjects to an area two or three hours' travel from their homes.

The remaining three suspects saw their Tpim notices revoked as two men - Mohammed Ahmed Mohamed and Ibrahim Magag - absconded and one is in prison, Mr Anderson added.

Mohamed was last seen fleeing a London mosque in a burka in November last year, while Magag vanished in a black cab on Boxing Day 2012. Both are still missing.

Mr Anderson said reintroducing constraints on location would "reduce the abscond risk" and "rebuild confidence in Tpims" after Magag and Mohamed went missing.
