Detectives from the Kent and Essex Serious Crime Directorate are appealing for information following an aggravated burglary in Dover.
The incident happened at a residential address on Tower Hill at about 10.30pm on Thursday (7 December 2017).
E-fits have been released of two men who reportedly forced their way into the property after the owner answered his front door to them.
He was then assaulted and threatened with further violence before being forced to hand over a significant quantity of cash.
The suspects then left the property with other items of value including a laptop computer and mobile phone.
Both men are described as being white, of stocky build and between 5ft 10in and 6ft. One had dark hair, was in his mid to late 30s and was wearing a black body warmer and tracksuit bottoms, while the other was wearing a puffer jacket with grey sleeves and tracksuit bottoms.
Anyone with information is urged to call the appeal number on 01843 222289 quoting reference 07-1382. Alternatively call Kent Crimestoppers anonymously on 0800 555111.
