Something similar happened here in America. Well, similar in the fact that some pizza delivery dude had a bombed strapped to his neck.
Unfortunately his bomb went off, and he died. It really was like in the movies though, cause when all was said and done, it turned out the pizza delivery guy was in on it...
...See his accomplices convinced him that if he had a fake bomb strapped to his neck, he could rob a bank and get off free with it. Then, his accomplices put a real bomb on him with the assumption, that once he delivered the money, they would simply let it explode and kill him.
The way it played out however, he robbed the bank, but then was surrounded by police, who tried to disarm the bomb. As you already know, this did not work out. If I remember correctly he was the only one hurt though. Oh, and to make things a little worse, the guy was legally retarded, so there's that too.
The good news is, all of his accomplices were caught and brought to justice.
In fact, heres a link, the guys name is Brian Wells
