Investigators have not yet determined the cause of the fire that damaged the Pink Triangle on San Francisco's Twin Peaks.
The arson took place Sunday morning, just a few hours prior to the city's annual Pride Parade. The ornament, a pink fabric triangle, is installed each year on a hill at San Francisco's Twin Peaks.
The triangle is a historically loaded symbol of gay oppression and was once used by officials in Nazi Germany to identify and discriminate against gays. Since then it has become a symbol of gay liberation as well as a way to pay tribute to those who were oppressed and tormented by the Nazis.
The fire was reported at approximately 5 a.m. and was extinguished about a half hour later. No arrests have been made yet, police said.
