A man accused of trying to murder a postman by pushing him in front of a train at Oxford Circus tube station said he carried out the attack because of a “dirty look”, a court has heard. Brwa Shorsh, 24, shoved Tadeusz Potoczek without warning from the platform just a few seconds before a Victoria Line train was due to arrive. Mr Potoczek, who was on his commute home, was pulled to safety by a man on the platform, while the quick-thinking train driver slammed on the brakes with seconds to spare to avert disaster, Inner London crown court heard. “It’s the stuff of nightmares”, said prosecutor Sam Barker. “A case of shocking and random violence.”When he was arrested, Shorsh - who denies intending to hurt Mr Potoczek - told police that he was “angry” after believing three women on a passing train had been rude to him.
