There had been a situation where a small number of police officers had become outnumbered by protesters in Cornhill, and had retreated into the pedestrian street, Royal Exchange Buildings. It was like, anything could happen right now. Riot officers began to arrive and within minutes the police had regained control around the Threadneedle Street end where I went to stand.
At this point there were probably about 20 officers - some dog handlers, some riot officers. And members of the public - city workers, people watching - were being stopped around the traffic lights although some were being allowed to walk through the pedestrian street that was now relatively clear, with a few protesters still standing around but certainly not a crowd.
The dog handlers began to sweep through the pedestrian street to start forming a police line. A dog barked and I saw one protester was on the floor who managed to get up. That's what drew my attention to that spot. It was then that I noticed Ian Tomlinson, who was walking from Threadneadle Street direction, walking towards Cornhill Street. A riot police officer had already grabbed him and was pushing him.
It wasn't just pushing him - he'd rushed him. He went to the floor and he did actually roll. That was quite noticeable. It was the force of the impact. He bounced on the floor. It was a very forceful knocking-down from behind.
The officer hit him twice with a baton when he was lying on the floor.
So it wasn't just that the officer had pushed him - it became an assault. And then the officer picked him up from the back, continued to walk or charge with him, and threw him. He was running and stumbling. He didn't turn and confront the officer or anything like that.
