Media coverage of the G20 protests has focused almost entirely on the violence outside the Bank of England and, following the release of Guardian footage, the tragic death of Ian Tomlinson. Events at the Bishopsgate Climate Camp, which was cordoned off in an aggressive operation by riot police, went largely unreported by the BBC and other major media outlets. Most of the reporting has come from online sources (see Stuart White and Beth McGrath for example). Here we publish another eye-witness account of the aggressive police action.

Chris Abbott: I went down to the climate camp after work on Wednesday as I had heard that it was completely peaceful and I wanted to see what it was like. Unfortunately, I got trapped there when the police first charged and then penned everyone in early in the evening and none of us could get out (this was about 7.00-7.30pm). Footage of this is now on YouTube. During this first, entirely unprovoked, attack I lost my girlfriend in the crowd - but I later found out she was punched by a policeman while trying to stop another girl being trampled on after being knocked to the floor.

Once that had calmed down, my girlfriend and I found each other and were sat with others in front of the line of riot police on the south side of Bishopsgate. It was completely peaceful once again and we were even joking and talking with the police. We were there for a couple of hours when they suddenly charged again without any warning (this was about 9.30-10.00pm). We were still sat down and offered no resistance at all. My girlfriend was pressure pointed on the neck (extremely painful), dragged backwards off me and had both her wrists bent behind her back by two policemen who threatened to break them. They dragged her outside the police cordon and then said "what should we do with her now?" before the other said "let's throw her back in", which they did - head first, with her hands behind her back. She landed on the floor and has now got severe bruising on her legs (which we have photos of) and very painful wrists (which we actually thought might be broken).
