bricks

Riot police were attacked with bricks and fireworks last year, despite the restrictions, and a female police officer was injured when the window of her vehicle was shattered.

Blaenavon Ironworks' Cast House was recently closed to the public after a visual display was vandalised and bricks thrown from the top of a tower.

It advised some of the construction debris dumped at the site - concrete, bricks and glass - could remain in place as those materials do not cause water pollution.

"It was coming down the side street off the side of the pub like a river. It was bringing bins, bricks and debris down the street."

Their new homes are metal containers, rather than bricks and mortar.
