Detectives are appealing for witnesses and information about a robbery in the Acomb area of York.
It happened at about 4.50pm on Friday (22 May 2015).
The victim, a local man aged in his 20s, was walking along a cycle path leading from Danebury Drive towards the Morrisons supermarket.
He was approached by two unknown men on pedal cycles who punched him to the floor, searched his trouser pockets and attempted to steal his bag.
The victim was then kicked in his ribs and head resulting in hospital treatment, including stitches to his face.
The suspects made off empty-handed towards Woodlea Avenue after the victim shouted “police”.
The victim remembers seeing a man walking a dog at the time of the robbery.
Police are particularly appealing to the dog walker to come forward who may not have realised what was happening.
One of the suspects was riding a red and white mountain bike and is described as white, aged between 20 and 30, and was wearing a black baseball cap and black hooded top.
Anyone with information that could assist the investigation is urged to call DC Kevin Goodman from the York Serious Crime Team on 01904 669453.
Or call Cimestoppers anonymously on 0800 555 111.
