The questions that need answering after the London Bridge attack

We learnt this weekend that the London Bridge attacker, Usman Khan, had been jailed in 2012 along with eight other men for terrorism offences, and had close links to the group planning to bomb the London stock exchange, among other targets. If so, why was he allowed to travel to the heart of London while released on licence? It is highly likely that he would have been restricted from travel to London and that the probation service and possibly police therefore gave special permission for him to attend.

The Sunday Telegraph’s coverage indicated as much yesterday. So it looks as if there has been a fatal error here: Khan hoodwinked the authorities into letting him attend an event near London bridge presumably because its theme was rehabilitation and prison education. The Telegraph also says he attended a previous event – on Whitehall – earlier this year, but with a police minder on that occasion.
