A frail pensioner was robbed of thousands in holiday money by an attacker who followed him home in Enfield, north London.
The 84-year-old man was knocked to the ground in Wades Hill, in an assault condemned by police as "vicious and sickening".
Officers suspect the attacker followed the man by car after spotting him pocket €4,000 (£2,900) at a local money exchange shop.
When near the victim's house, the attacker leapt from a car near the victim's home and knocked him down, before snatching the money from the elderly man's pocket. Leaving him on the ground, the assailant sped away in a grey Audi car from the scene.
The OAP broke a bone during the attack and was taken to hospital where he is in a serious but stable condition.
Detective Constable John McCarthy, said: "This was a vicious and sickening attack on a vulnerable elderly man who had exchanged money ahead of a holiday with his wife. There is a strong indication that he was targeted and followed by the suspect from the money exchange shop in Oakwood.
Police say the offender was east European in appearance, aged in his mid-20s with short black hair and a moustache. He was wearing a black Parker-style jacket with a fur-lined hood, blue jeans and black shoes.
Anyone with information is requested to call police on 101 quoting reference 5206085/15.
