A woman who complained of a racist and misogynistic culture in a Scottish government department claims she was taped to a chair and gagged by two male colleagues as a warning to keep quiet.
DeeAnn Fitzpatrick said the restraint took place amid years of bullying and harassment at Marine Scotland's Scrabster office.
The fisheries officer has taken her case to an employment tribunal.
BBC Scotland has obtained a photo of the restraint incident.
It was taken by one of the men allegedly responsible.
Ms Fitzpatrick, a Canadian national, said it happened in 2010 as a result of her blowing the whistle on a threatening and misogynistic culture at Marine Scotland's office in Scrabster, on the far north Caithness coast.
In evidence to her ongoing tribunal, she said that one of the men involved, fisheries officer Reid Anderson, told her: "This is what you get when you speak out against the boys."
