UPDATE: Detectives are calling for the public's help to find the men who threatened a 67-year-old man in his Caversham home last night.
The victim, Dominic, was not injured in the incident but was left shaken when he was threatened with a knife.
Two masked men forced their way through the front door of Dominic's Alsace Avenue house between 6.40pm and 7pm.
