Kent Police is appealing for witnesses following a report of a burglary in Dover.
It was reported that during the afternoon of Sunday 12 February the victim, a man in his 80s, answered the door to a man asking for money to buy petrol. The man left after the victim gave him some money.
Between 5.30pm and 6.30pm on Monday 13 February 2017, the man returned, and forced his way into the property, shutting the victim into a downstairs cupboard. The suspect then left the property in Branch Street, Dover.
The suspect is described as a white man, aged 20 to 30 years old, around 6 ft tall, with a stocky build and an English accent.
Detective Sergeant Matt Smith said: "This was a nasty incident which left a good Samaritan shaken, but fortunately he suffered only minor cuts and bruising.
"We would ask anyone who might have seen something in the area on either day to contact us as it could prove invaluable to our investigation."
