Investigation launched into Doncaster robbery – can you help?

Police in Doncaster have launched an investigation after a man was the victim of a robbery earlier this morning (Monday 12 February). 
At around 10.50am, a 28-year-old man was walking towards the train station along a pathway that runs from Marshland Road, Moorends, along the back of the train tracks, when he passed two other men, both described as in their early 20s. 
One of the men is then said to have pushed him to the floor, before the second man reportedly threatened him with a knife, described as a small kitchen knife. 
The two men then took the man’s rucksack and a H.Samuel jewellery bag he was carrying, before heading towards the railway. 
The victim then left the area, going back towards Marshland Road. 
PC Alex Rowley, investigating, said: “Although the man wasn’t injured during the incident he has understandably been left extremely shaken by what happened and an investigation is now underway to identify those involved. 
“From our enquiries so far we know that there were a number of women stood at the bus stop on Marshland Road, looking in the direction of the incident. I’d like to appeal to them to come forward, if they saw the two men, saw what happened or have any further information. 
“The first man is described as white, slim build and about 5ft 8ins tall. He is described as wearing a burgundy hoodie with JD written on the front, black Adidas jogging bottoms with stripes on the knees and riding a grey mountain bike. 
“The second man is described as white, with ginger hair, about 6ft tall and of a muscular build. He is said to have been wearing black and burgundy tracksuit bottoms, a red/brown hoodie and brown/maroon trainers. 
“If you have any information, please get in touch with us either via 101 or Crimestoppers anonymously on 0800 555111.”
