A four figure sum was taken from the woman's account
A woman in her 80s has lost savings in a scam aimed at bank customers in the Highlands, it has emerged.
Northern Constabulary said her case highlighted how the vulnerable were being targeted in unsolicited telephone calls and e-mails.
The force said that callers were claiming to be representing high street banks.
Police urged people not to disclose personal and bank details if contacted and to report suspicious calls.
The incident involving an 84-year-old woman, from Inverness, who did not wish to be named, saw her lose a four figure sum from her account before she discovered the loss.
Sgt Gus Stewart, an officer based in Inverness, said: "This is a particularly callous act, especially given the age of this woman and we would again warn people not to give out their bank account or personal details to anyone over the phone."
Police said a number of similar frauds were reported over the weekend and in the past month more than 30 people had complained about money going missing from their accounts, or members of the public wishing to inform police of suspicious calls relating to their accounts.
