Police are looking for “professional criminals” who stole a diamond ring worth £56,000 from a shop in Leeds.
Officers have released CCTV images of two people they want to find after the incident at W Hamond jewellers in the Victoria Quarter.
The man and woman went into the shop on Monday and asked staff to show them various items.
While the assistants were distracted they stole the ring from a display board and left.
PCSO James Hudson, of the City Neighbourhood Policing Team, said: “It is believed these two are professional criminals who travel around committing offences of this type as they are confident and appear well practised at this type of offence.
“As well as appealing for information to identify them we hope this publicity will serve as a warning to other jewellers to be aware of these offenders. We’d also like to hear from anyone who may have been offered such a ring for sale.”
The man was Asian, in his late 30s to 40s, of medium build and with short dark hair.
The woman was of similar age, about 5ft 2ins tall and wearing a black headscarf. Both had gold teeth.
Anyone with information should call police on 101 or call Crimestoppers on 0800 555111.
