Police are hunting doorstep conmen who tricked an elderly Sunderland woman into buying fish for a "significant amount of money".
It happened between 3pm and 4.15pm on Wednesday, July 7, when three men selling fish called at an address in Grindon Park.
Three men were seen driving around the area at the time and Northumbria Police are keen to identify them and are asking anyone who was in the area and saw the men to let them know.
Police also want to remind people to take steps to avoid falling victim to doorstep crime and to be cautious of people calling at the door unannounced - whether they are selling goods or claim to be from a utility company, local authority or even police.
Acting/Neighbourhood Inspector Phil Baker said: "Bogus callers often target elderly or vulnerable people and we are are asking anyone with an elderly or vulnerable relative or friend to make sure they are aware that not everyone who calls at the door is who they claim to be, it can also help to leave a note by the front door to remind them.
"Genuine callers will not mind waiting - or coming back another day .
"Extra officers will be in Grindon over the next few days to offer reassurance and advice to local residents and anyone concerned should not hesitate in speaking to an officer."
Any witnesses can contact Northumbria Police on 101 quoting reference 721 130716 or Crimestoppers anonymously on 0800 555 111.
