The incident took place at approximately 9.40am on Thursday 11 October 2012 in the Parkwood Road area of Boscombe.
The victim, a 64-year-old man from Boscombe was threatened and made to hand over property including a laptop and cash. He sustained minor injuries.

Detective Steven May, of Bournemouth CID, said:
"This was a nasty attack and we are keen to identity the offender as soon as possible.
"It happened at a time of day when people were around and it is possible someone saw something suspicious.
"The man responsible may have injuries to his hands from bushes when he ran from the scene.
"I appeal to anyone who may have any information to contact Dorset Police as soon as possible in the strictest confidence."
The offender is described as a white man in his 20s, approximately five feet 11 inches tall, of skinny build with short close cropped hair. He was wearing a dark coloured, possibly navy jacket, dark coloured trousers and was carrying a purple rucksack.
