This is annoying me because the media keep saying he was on the run but - as far as I can tell - he was let out under very strange circumstances (in prison tracksuit etc), is not a native English speaker and probably didn't have a complete understanding of what was happening.
At what point would a mistakenly released prisoner say "I think you have made a mistake"? Particularly one with limited understanding of the criminal justice system.
The crime he committed was terrible and I am glad he is being deported, but his mistaken release was not his fault and he didn't really go "on the run", just got on with the situation he was presented with.
