Police in Cardiff are investigating burglars, who tricked two elderly people in distraction thefts only minutes apart.
It is thought the same offenders are responsible for the incidents in the Whitchurch and Birchgrove areas.
The first was at Pantbach Road at about 1900 BST Saturday at the home of a 93-year-old woman, the second shortly after in Clas Illtyd.
The men posed firstly as water workers, then as window cleaners.
Anyone with information is asked to call Fairwater CID on 029 20528013.
In the first incident, a slim, clean-shaven man wearing a white shirt called at the home of the 93-year-old woman claiming to be working at a nearby house and asked to check her water supply.
She was asked to flush her toilet several times, but the man left with jewellery, cutlery and her purse.
He is described as being in his mid 20s, about 5ft 6ins tall, and had an accent described as not Welsh.
In the second incident, two men claimed to be collecting money for window cleaning and followed the 83-year-old male occupier into his house, stealing his wallet.
They left in a dark car described as "expensive-looking and low".
Both men were white, in their 20s and wearing dark clothing. One was around 6ft tall, the other about 5ft 6-8ins.
Det Sgt Chris Cullen from Cardiff CID said: "We wanted to advise people of these incidents as soon as possible in case these men call at any other properties in the area."
Police are advising people not to allow strangers into their homes.
