BURGLARS posing as police have been preying on the elderly.

Crooks struck at two homes in the space of an hour on October 20, each time getting away with an unspecified amount of cash.

Their first victim was an 87-year-old woman in Worton Way, Isleworth.

At about 9pm an 85-year-old heard a noise from the hallway of her home in Wesley Avenue,

Hounslow. When she disturbed the burglars they said they were police and asked where her money was.

The burglars are all white men. One is aged 40-45, about 5ft 7in and had short dark hair. He was wearing a black top and a flat cap. Another is 30-35, about 5ft 8in and had short brown hair. The third is 20-25, 5ft 11in and had short dark hair and a dark top with a white emblem.
