A disabled OAP, sat in a wheelchair, has been pushed off a railway station platform by a stranger who offered to help her get on board her train.
The man then jumped on to the tracks himself, picked up a large rock before smashing it repeatedly on the defenceless 72-year-old woman's head.
Horrific CCTV caught the entire scene on film, including the moment selfless commuters raced on to the tracks to stop the attacker hurting her.
The woman, who was on her way to hospital from her home town of Czestochowa, in Poland, had to change trains at Leszno.
