Detectives investigating the theft of a diamond tiara that's been described as a "national treasure", have released CCTV video and pictures of three suspects.

The Portland Tiara was stolen from an armoured display case at The Portland Collection Gallery at the Welbeck Estate in Worksop in Nottinghamshire last month.

The centre-piece of the tiara is the Portland Diamond, which dates from the 19th century. It's flanked by two diamond drops and other pendant diamonds, all set in gold and silver. It was taken along with a diamond brooch - while the alarms were sounding.

Nottinghamshire Police say burglars broke into the gallery between 9.45pm and 10pm on Tuesday 20th November.

Officers are also appealing for information about a silver Audi RS5 Quattro, with the registration number KY61 USJ, which is thought to have been involved in the burglary. Police say it's the same model as the car pictured.

They say the Audi was stolen from the Phoenix Park Park and Ride tram stop on Millennium Way East in Cinderhill on Friday 2nd November.

It was later found abandoned and burnt-out on Cross Lane in Blidworth around half-an-hour after the burglary.

"Our enquiries are ongoing and we're making a plea to potential witnesses.

The suspects were wearing white suits and motorcycle helmets but we're still hoping someone may know who they are and we're urging anyone with any information to get in touch with us.

We're also urging anyone who has any information about the silver Audi RS5 to contact us.

Did you see this car in the area around the time of the burglary or have dash-cam footage of it? Did you see anyone in the car ?

We're keen to trace this vehicle's movements preceding the burglary so again we're appealing to anyone who saw it or who has any information to get in touch with us as soon as possible.

We believe the burglars used specialist diamond cutter-type tools to break through the armoured glass display case. If anyone has information about people hiring or sourcing such equipment then we’d urge them to get in touch."

– Detective Inspector Gayle Hart
