Police are hunting for a man - possibly multiple men - who burst into the house of an elderly woman and forced her to buy fish.
A man burst into the property and shoved fish into the freezer of a 96-year-old woman and demanded £100.
On Friday, a man or possibly two men knocked on the window of a woman's house in Eggborough, near Selby, North Yorkshire.
A man was seen waving at the window for the woman to open the front door. She was then told that 'someone down the road' had ordered £100 of fish for them and that they owed £100 for it.
Without invitation, the man then walked into the property, put fish into the freezer and told the victim it was worth £60 and she would have to pay for it.
The victim 'felt intimidated' and wanted the man to leave, so paid up and the offender left.
A spokesman for North Yorkshire Police said: "Remember, if you're not sure who is at your door don't open it! ]
"Check the identity of the caller by calling the company they are purporting to be from or telephone a neighbour or friend nearby to come and assist. If you suspect a bogus caller has visited, even if they did not enter your address, report to the Police straight away.
