Shock figures published on Thursday that only one of 2,000 people in the UK suspected of being radicalised by terrorist groups has been subjected to a curfew by police have been challenged by an expert in international security.
Raffaello Pantucci, director of international security studies at the Royal United Services Insititute, has disputed the effectiveness of the curfews – known officially as Terrorism Prevention and Investigation Measures, or T-Pims – and suggested that security services have simply chosen different methods to monitor potential jihadists.
T-Pims are intended to be used to 'curb the freedoms' of suspects not formally charged or deported.
"The question about T-Pims is 'how effective are they?'" he explained to Julia Hartley-Brewer.
"There are a couple of people who fled the country while under them, so it wasn't clear these were effective tools.
"What you have probably seen [with the one in 2,000 figure] is that the police and security services are using other tools to try to deal with [these people].
"They have concluded that T-Pims, as they are currently structured, are not necessarily the right answer."
