Police have released CCTV images of two men after suspected bogus charity collections in York.
Officers said the men pictured were collecting donations for Cancer Research UK in the Marks and Spencers store on Pavement in York on Thursday, January 18 and Friday, January 19.
In an appeal, North Yorkshire Police said they were dressed in the charity's branded tabards and carrying branded buckets.
Police said that when questioned by store staff, the men could not provide the relevant paperwork required to legitimately collect in the store.
When store management checked their identification with Cancer Research UK, the charity confirmed that the men were not known to them, according to the force.
Anyone who recognises the men pictured, or anyone with information, is asked to contact police 101, select option two and ask to speak to PC Becky Lawrenson. People can also email Rebecca.Lawrenson1998@northyorkshire.pnn.police.uk.
