Police in Londonderry have repeated advice to elderly people to be aware of callers to their homes.
The warning comes after a number of pensioners were targeted in recent days, including two elderly sisters who were held at knifepoint while two men ransacked their home.
The attack on Sadie (78) and Bridie (84) Ramsey happened just 24 hours after a 6ft 4ins red-haired man forced his way into the home of a couple in their 70s living in the Francis Street area of the city.
Police continue to search for this man who was described as “well dressed, aged in his late 30s or early 40s with a southern accent” in connection with the incident.
Neighbourhood Sergeant Sam Young said it is important for everyone to be mindful of strangers calling to their homes but particularly elderly people who may be viewed as easy targets. He added: “Bogus callers depend on the good nature and good will of others.
“They tend to target the more vulnerable members of our society. It is always advisable to be cautious of unexpected callers, think before you open the door.”
