The thefts took place at on two occasions from Marks and Spencer on Cambridge Street:
- at around 4.30pm on Sunday 21 September 2014
- shortly after 12noon on Monday 22 September 2014
The man is described as white, around 6ft 4in tall and short brown hair. At the time he was wearing a white t-shirt, a striped hooded top, grey jogging bottoms with bright orange stripes.
PC Brendon Frith, of Harrogate Safer Neighbourhood Team, said: It may be that the two people captured on camera had nothing to do with the thefts.
If this is the case I urge them to come forward straight away so I can eliminate them from my enquiries.
I am also keen to speak to anyone who recognises either of the people and ask them to get in touch with me as soon as possible.
Anyone who can assist with this investigation should contact Harrogate police on 101, select option 2 and ask for Brendon Frith.
