GETTY Germany is introducing ankle bracelets for terror suspects

The measure will allow the police to track the movements of a person deemed a security threat before they have been convicted of any crime. Until now only convicted individuals could be required to wear the device used to monitor location and movements.

Ankle bracelets are not a panacea but they are an important instrument to facilitate the surveillance of dangerous people Interior Minister Thomas de Maiziere

Interior Minister Thomas de Maiziere said: “Ankle bracelets are not a panacea but they are an important instrument to facilitate the surveillance of dangerous people.” The German cabinet approved the measure as a series of anti-terror raids on mosques and private addresses were carried out across the country. Electronic tagging is part of a raft of beefed up security reforms announced in response to the horrific December 19 attack in which Tunisian national Anis Amri ploughed a truck into a crowded Christmas market in Berlin, killing 12 people. Amri was shot dead during a brief gunfight with Italian police in Milan several days later.

Public anger quickly erupted after it emerged that Amri was already on the radar of intelligence services and was known to have links to Islamist radicals. As a failed asylum seeker, he should have been deported months before the attack but Tunisia failed to send the necessary paperwork in time. The German government has since vowed to speed up deportations and is considering plans to place rejected asylum seekers who are considered a threat in detention ahead of their expulsion.
