"Or are you struggling with the bit from your own link that says: arrested on suspicion of carrying a knife?"
I think it's you, who is confused.
Don't worry though, i'm a patcient person and will try to explain to you, how this resulted in him not having a knife, but why he got arrested on suspeicion.
As you know, the man threatened to stab some people. This gives the suspicion, that he has a knife.
therefore, he was arrested on suspicion of having a knife.
After further examination, and searching, there was no knife found. You know how i know this? He wasn't charged, he wasn't penalised, it was never mentioned if he had a knife on him in the numerous reports. This indicates, because we've not been told, he didn't actually have a knife on him.
He was then arrested for theft from finding.. and taken to a cell.
IF the guy had a knife on him, it would have been reported. It's as simple as that.
If you think being arrested on suspicion means you're guilty, then oh my you're in for a shock.
