The first female Beefeater has complained of being subjected to a bullying campaign by some of her male colleagues.
Two male Beefeaters have been suspended and a third is under investigation for harassing Moira Cameron, who became a Beefeater at the Tower of London in July 2007.
One employee at the Tower of London is also thought to have received a police caution after defacing Cameron’s Wikipedia page.
Cameron has claimed that while she lived at the Tower with 34 male colleagues her uniform was tampered with and notes were left in her locker.
An internal investigation was launched last weekend (24-25 October) into Cameron’s claims, the Guardian has reported.
When Cameron first accepted the job she admitted some of her colleagues were not supportive.
She previously said: “I’ve had some comments. I had one chap at the gate one day who said he was completely and utterly against me doing the job.
“I said to him, ‘I would like to thank you for dismissing my 22 years’ service in Her Majesty’s armed forces’.”
In a statement the Tower of London said: “We can confirm that three yeoman warders are under investigation in response to allegations of harassment. Two have been suspended.
“We take such allegations very seriously and our formal harassment policy makes it clear that this is totally unacceptable.”
The internal investigation is expected to conclude in two to three weeks.
Cameron’s main duties include guarding the tower – including the crown jewels – and welcoming tourists.
