It is alleged that the couple put the razor blades in the doughnuts of the store, which is in the mall where the couple work, before eating them in an attempt to claim damages from Smith’s Food and Drug shop in Draper, Utah.

It is also alleged that they handed one of the razor blade doughnuts to a colleague working alongside them in the same shopping mall.

According to reports the colleague suffered cuts to her mouth, prompting her to contact police.

It is alleged the couple planned to extort money from the store after calling police to say they had found a a piece of sharp metal in a doughnut.

Draper Police Sergeant Chad Carpenter said it became clear that “things weren’t adding up” after detectives had examined the evidence.

"During the course of the investigation we were able to determine that they intentionally inserted these broken razor blades into doughnuts that they had purchased at Smith's and then swallowed the razor blades with the doughnuts," police said in a statement.

Investigators say they became suspicious about the couple's claims when they realised that the doughnuts were in tamper-proof packaging.
