From 'On One'
I saw that. It was pretty nasty, I was heading West from Tooley St to Southwark St.
We pulled away from the lights together (big 6-wheeler lorry and a few cyclists, all turning left) and when I got under the railway bridge I heard a horrible crunching of metal and looked around to see this guy, well basically on the ground and his legs being ran over by a massive lorry.
The lorry driver jumped out, the cyclist was screaming and flailing and people ran over. Somebody picked up his bike in pieces and I carried on to work.
The cyclist was on the right of the lorry, and the driver didn't see him. It wasn't articulated but it must've clipped him as it was turning.
