The incident took place at around 11.10am on July 30 at a property on Beach Road, Fleetwood when a man entered the property through the front door, before being confronted by the wheelchair-bound occupant.
He stated he was waiting for his mother and entered the lounge and sat down by a table at the window.
He then stood up and opened drawers escaping with a purse containing around £10, a wallet containing around £50 and a black handbag containing two pairs of glasses.
The offender is described as a white male, aged around 19 or 20, tall and of slim build, with short dark-coloured hair and a local accent. He was wearing a light grey fleece-top with a white zip and possibly grey trousers or jogging bottoms.
