A cyclist who knocked down a pedestrian on a busy London street, later blamed his victim saying people have "zero respect" for those riding bikes, a court has heard.

Charlie Alliston, who was aged 18 at the time of the accident, was said to be going nearly 20 mph, when he ploughed into mother-of-two, Kim Briggs, 44, as she crossed the road during her lunch hour February 12 last year.

Mr Alliston had been riding a fixed wheel track bicycle with no front brake, which is illegal on British roads.

He allegedly shouted to her to "get out of the way" twice before their heads smashed together.

Mrs Briggs, an HR consultant suffered "catastrophic" brain injuries including two skull fractures and died a week later.
