Lucy Roberts, aged 39, routinely took jewellery home during the year she was employed at a luxury retail store, the police noted. She would tell her skeptical coworkers that she was “conducting work at home and organizing stock for the workshop.”

The police statement does not name the store.

It was only when Roberts quit and went on holiday that her colleagues realised where the jewellery went, the statement says.

She began sending her former coworkers selfies from a cruise, decked out in items taken from the shop.

“Completely unfazed, adorned with diamonds, she believed she had tricked everyone,” stated Detective Sergeant Krista Wilkinson in the police’s press release.

Police found “thousands of pounds worth of jewellery strewn around in boxes beneath the bed and in cupboards,” after searching her home, the statement says.

In total, Roberts stole more than $260,000 in diamonds, gold, silver, “bespoke jewellery” and cash from her employer, according to Wilkinson.

CNN was not able to determine whether Roberts has legal representation.

Police said Roberts initially denied she had stolen any stock from her employer, insisting she had borrowed some of the jewellery from a coworker and that they planted the other items in her bags, but she later entered a guilty plea for theft by an employee, receiving 28 months in prison.

Roberts was arrested at London’s Heathrow Airport, according to police.

They took her into custody after finding her “wearing a substantial amount of stolen jewellery” with more pilfered merchandise in her suitcase, according to the statement.

Body camera footage from the arrest shows Roberts removing more jewellery as she was escorted through Heathrow Airport … in an attempt to dispose of it,” police added.

The store where Roberts formerly worked said it is “pleased to finally have closure on the matter after several years,” according to the news release.
