Brazilian woman loses arm after being pushed in front of Sao Paulo subway train

The graphic images - captured on a camera in the tube driver's cab - shows the casually-dressed suspect running up behind his victim and shoving her onto the track as the train enters a packed underground station in the Brazilian city of Sao Paulo.
The attacker, who targeted Maria da Conceicao de Oliveira at random, ran away laughing, according to witnesses.
The horrific attack happened just after 7am at Se Station, the busiest tube station in Sao Paulo, during Tuesday morning's rush hour.
Maria, who turned 28 the day of the horror incident, was rushed to hospital where medics amputated her right arm to save her life.
Police are hunting a man wearing a white T-shirt and black trousers seen running from the scene.
He is said to have tried to have steal a handbag and harassed another woman before targeting Maria, who is currently 'stable' in a city hospital intensive care unit.
Friend Ana Livia de Souza said: 'Maria has told me she feels born again and the accident was very ugly
