Finlay Wilson became an internet star when he showed off his buns while doing yoga in a kilt last month, but the increased attention has come with some negativity.
The Dundee native’s revealing clip with Tristan Cameron-Harperin was viewed more than 50 million times, however he has received homophobic abuse as a result of it.
A handwritten note was left on his doorstep on Tuesday, which threatened his safety, and that police are now treating as a hate crime.
“I came out my flat at 06.30 in the morning to walk the dog and there was a handwritten letter in a sealed envelope on the front step addressed to ‘the gay boy at number 45’,” Finlay told BBC News.
“I don’t really know anyone in the building. My friends have been saying they didn’t realise this sort of thing still happened in this day and age.”
He added: “I was upset at first, but now I am furious, because someone’s aim is to intimidate me and terrorise me into leaving my home because of their own bigoted beliefs.
“The people who do this sort of thing need to know that their views are unacceptable and the majority of people won’t tolerate it.”
Finlay revealed that they also threatened his dog’s life.
“I’ve had to put a cage on the letterbox to make sure they don’t post anything harmful through that he might eat,” he said.
Responding to the hate crime, a Tayside Division spokeswoman said: “Police Scotland does not tolerate hate crime in any form and everyone has the right to live safely and without fear.”
