A homeless man has  admitted knocking a frail 92-year-old widower to the floor to steal just five pounds. Stanley Evans, who lives on his own, was left lying on the ground for ten minutes after being attacked as he returned from a shopping trip in London. Soloman Bygraves had followed the pensioner, now 93, into his block of flats in Soho, central London, and pushed him over as he lunged for his wallet. The assault, which has been branded by police as 'totally unprovoked, callous and sickening', came just months after the elderly man had given his attacker £10. Bygraves, 29, of no fixed address, pleaded guilty at London's Southwark Crown Court via video-link from Wandsworth Prison. Wearing a grey tracksuit, he spoke only to confirm his name and plead guilty. Mr Evans, who suffered an shoulder injury, eventually managed to get to his feet and take the lift to his flat to call 999. He did not require hospital treatment. The retired cameraman who worked on films including the 1947 classic Brighton Rock with Richard Attenborough - said he had been left 'flailing like a seal' after the attack. Speaking before the arrest, Mr Evans described the attack: 'I've gone past anger, I'm frustrated. If I ever came across that one again I was a boxer and aggressive, if someone punches me I punch them back.' 'I was coming up to my flat from the supermarket with a trolley when I saw a large black man sitting on the wall, I vaguely recognised him as someone I had gave £10 to last year. I'm quite friendly with people in the area. 'He was even helpful with the trolley. I left him sitting on the wall and started fiddling with my key. Then he was behind me. He told me he had come to visit someone on the second floor. Scroll down for video .

'When you fall over at my age every bit of your body hits the ground, I was flailing like a seal. It's almost impossible to pick yourself up. 'I waited 10 minutes for someone to come but nobody did.
