Haul mostly Pandora jewellery stolen from Stokesley branch.
Whittakers Jewellers in Stokesley has lost more than £100,000 of stock after it was raided in the early hours of Saturday.
The robbery is not connected to the riots that have been sweeping the UK. North Yorkshire Police have said that it may be a premeditated attack with the thieves suspected of visiting the shop earlier in the week to check it out.
The stolen stock was mostly Pandora charms and silver jewellery and police are asking retailers to be vigilant if they are approached by unauthorised persons selling Pandora jewellery.
Whittakers co-owner Nigel Evans said that the thieves broke through the front of the shop and that his sister Natalie, who he runs the business with alongside their brother, raised the alarm.
The Stokesley branch of Whittakers is on the same street as a police station, prompting Evans to call the attack “brazen”.
The shop was forced to close for a day, missing out on precious trading time. None of the staff were hurt in the raid.
Police have arrested three men from Middlesbrough in connection with the incident and have been released on bail.
