Police are appealing for information after an elderly woman and her son were robbed in their home in Knott End.
Two men knocked on the door of the pensioner’s home in Ambleside Avenue and when she answered the door they forced their way in and stole a quantity of cash.
Detectives said the incident took place around 10.45am on Friday.
Officers are now appealing for anyone with information to contact them.
Det Sgt Kathryn Riley, from Wyre CID said: “This is a serious offence and I would appeal to any witnesses who were in the area at the time who may have seen the two men or any suspicious vehicles at relevant time to come forward and contact us on 101.
“Fortunately the occupants were not injured but they have both understandably been left very shaken and upset.
“I would reassure people that an investigation is underway and police patrols have been stepped up in the area.”
