The incident took place between 4pm and 5pm on Thursday, December 30, in the Craigie area of Perth.
After the suspect tricked the elderly occupant into letting her in, she distracted her and stole the cash before leaving.
Shortly before this, the suspect had used the same tactics of lying about being from a church to trick her way into another elderly couple’s house in Darnhall Drive.
They however became suspicious and asked her to leave before she could steal anything.
Police Scotland is now looking to trace the individual who has been described as a slim woman, possibly in her 40’s. She was wearing a light-coloured puffer-style jacket and was carrying a green or blue carrier bag at the time of the incidents.
Officers believe it is possible that she tried to trick other residents in the area at the same time and are asking anybody with CCTV or video doorbell footage of the suspect, to get in touch.
