The Esso garage on Harrogate Road in Ripon has been targeted by thieves who broke into the on-site Co-op store, during the early hours of Tuesday 16 April 2013.
A large quantity of cigarettes were stolen in the incident.
Police officers are now appealing to anyone who saw any suspicious people or vehicles in the area around the time of incident or has been offered any cigarettes for sale recently to get in touch.
Police also believe that the lights of the store were turned on during the burglary, which would have been unusual for that time of day, and are urging anyone who may have noticed to contact them.
Anyone who can help officers with their enquiries is urged to contact North Yorkshire Police on 101 – select option 2 – and ask for Detective Constable Sarah Lynch or Harrogate CID.
Alternatively, information can be emailed to firstname.lastname@example.org
