Ex-terror police chief: Attacker should have been banned from central London

The 28-year-old was freed on licence in December 2018 and was wearing an electronic monitoring tag when he launched a knife rampage before being shot dead by police on London Bridge on Friday. UK head of counter-terrorism policing Neil Basu said Khan had been subject to multi-agency public protection arrangements (MAPPA) and had complied with an “extensive list of licence conditions” following his early release. Richard Walton, who headed the Metropolitan Police’s counter-terrorism command between 2011 and 2016, said: “His licence conditions should have restricted him from visiting central London.” He suggested longer prison terms and better deradicalisation programmes within jails are needed to help stop offenders committing attacks after they are released. In a poolinterview, Prime Minister Boris Johnson said: “I have long argued that it is a mistake to allow serious and violent criminal to come out of prison early, and it is very important that wegetout of that habit, and that we enforce the appropriate sentences for dangerous criminals, especially terrorists.” (Pictured) Police officers at the site of the incident near London Bridge.     A police officer is seen in the city, close to the area of the incident.
