Eyewitness says workman 'impaled on railings'

I didn't see the accident happen, but I saw a bit of the aftermath.There was a lot of screaming and shouting.

One man was impaled on the railings. He looked in a very bad way, I think he was one of the men who died.

I think the people who received other injuries were all removal men too, or at least most of them were. They were stood on the pavement when the balcony gave way.
