Police are investigating reports of a fake police telephone scam, aimed at the elderly, after victims lose thousands in cash or valuables.
All those involved received a telephone call from a man claiming to be from Hammersmith Police.
One 83-year-old woman was then told that there had been fraudulent activity on her bank account and someone had been arrested.
She was told that her bank was under police surveillance and she should withdraw money. A courier would then pick it.
She did this, only to be called back and told it was a scam.
Other victims, who have lost valuable items instead of cash, have received similar phone calls.
Anyone who receives a call like this should contact PS Harry Wilson at Eastleigh police station on 101.
