Police are appealing for information after a vulnerable man was targeted by robbers in his Colne home on Saturday January.
The robbery took place around 6pm when two men have knocked on the front door of a 66-year-old man who lives alone on Oak Street.
When he has answered the door the men have bundled him to the floor and searched the property. They escaped with a bank book but it is not clear at this stage if anything more has been stolen.
Both men are described as white and dressed in dark clothing with hoods up.
Det. Sgt Nick Hodgeson from Pennine CID said: “This was a terrifying ordeal for the victim who also sustained minor injuries to his face and hands and we urgently need anyone with any information that could assist us with our investigation to come forward.
“Anyone with information should contact DC 2126 Julie Leigh on 01282 472644 or Lancashire Police on 101.”
