Jewellery belonging to the late wife of an 88- year-old man was stolen in a robbery at his Pertenhall home.
Police are now warning all older residents and those who live near them to continue to be extremely cautious about answering the door to unexpected callers.
The man answered a knock at the door at about 6.30pm on Friday, January 10, thinking a neighbour was calling on him.
When he opened the door he was confronted by three men who barged into the house with their faces covered.
They ushered the victim into his lounge where one of the offenders remained with him saying that he would be unharmed if he did as he was told.
The other two searched bedrooms upstairs stealing jewellery belonging to the victim’s late wife. The items included a wedding and engagement rings and gold watch.
The man was physically unharmed but left shaken following the incident.
The offenders left the scene in a dark coloured vehicle that was waiting along Kimbolton Road for their return. They then made off in the direction of Keysoe.
Det Con Kevin Howes, investigating, said: “This is an appalling offence on a defenceless member of the public and the police would like to speak to anyone with information or who can assist in any way.
“We want to alert the public to be cautious when answering the door, particularly during the hours of darkness.
“If you live near an older person or have an elderly relative, encourage them to ask questions beforehand to identify visitors before unlocking or opening the door.
“Often, we find it is alert neighbours that prevent burglaries happening when they spot unfamiliar vehicles or people acting suspiciously and call the police immediately. If we can send someone out quickly then we can often catch these criminals.”
If anyone can help with information, contact Det Con Howes direct on 01234 275356, or text the force control room direct on 07786 200011, or call independent charity Crimestoppers on 0800 555111. You do not have to give your name but you could still receive a cash reward.
