The sergeant in charge of PC Keith Blakelock's unit has described the "terrifying" moment they came under attack by a mob with iron bars and a machete. David Pengelly led his team of 10 officers to protect firefighters tackling a blaze at a supermarket.
It was a scene of considerable disorder. There were lines of officers with shields. There were missiles being thrown. It was a scene of considerable rioting.
I saw a group of youths. My eye was drawn to youths who were running underneath us. A group appeared at the far side of the level we were on from an entrance of some sort.
There was something perhaps of a dramatic pause. I do not know the reason. Then another group appeared slightly to the right from an unknown point to me.
There was no time to reflect as the second group immediately starting throwing items at us - bottles, bricks, I believe mainly.
