A mother known as the Pimlico Pusher shoved a pensioner towards a moving bus after a row in a supermarket, a court heard.
Amelia Doris, 40, was caught on CCTV attacking Linda Lancaster on Vauxhall Bridge Road, central London, on 29 May 2018.
Ms Lancaster, who is in her 60s, had tried to avoid Doris by walking around the block after the argument in Tesco Express in nearby Warwick Way.
But their paths crossed again at Vauxhall Bridge Road and Doris shoulder barged her head-first towards the moving bus.
CCTV footage showed Doris, accompanied by a small child, brutally attacking the older woman before fleeing the scene.
