Mr Tomlinson, 47, collapsed and died from a heart attack near the Bank of England after being caught up during the demonstrations on his way home last Wednesday. His son Paul, 26, said: "Through CCTV and pictures that I've been shown he got refused access on a number of barricades that police had set up. And the missing jigsaw puzzle was what happened to him when he got into Royal Exchange Passage. I think what we've just seen has answered a lot of questions."
Mr. Tomlinson was hit by a policeman.
