Police in Kingston, Ont., have launched a criminal investigation after a lesbian couple received two homophobic letters, threatening them to leave the city.

The letters were allegedly sent by a group that is “devoted” to driving homosexuals from the city.

“We know you and have been following you for the past several weeks and we wish for you to leave this city, before it is too late, for you,” the letter reads.

Det. Chris Gobeil told CTV Toronto that police were made aware of the letters mid-week and launched an investigation.

One of the letters indicates that the group has successfully driven out gay couples from Kingston in the past.

However, Gobeil said he is not aware of any other incidents of same-sex couples being threatened to leave town.

“The community response has been unanimous,” he said. “Dismay, upset and disgust.”

Gobeil said no suspects have been identified, and anyone with information is asked to contact police.
