The leader of a protest against a drag queen story time event in Brisbane, Australia, has reportedly died by suicide just a day after he and his fellow disrupters stormed a library.

The doors of Brisbane Square Library blew open on Sunday as around 15 to 20 students from the University of Queensland Liberal National Club aggressively accosted two drag queens reading books to children.

Wilson Gavin, the club’s gay president, was found dead at Chelmer Railway Station this morning at 7:07am. Ambulance officers rushed to the scene, but said he died from critical injuries, Buzzfeed News reported.

No other details were provided by medics.

Drag queen demonstrated against expresses her grief over Wilson Gavin’s death.

The then 19-year-old jolted into the public for his passionate opposition against same-sex marriage – actively campaigning against the postal survey in 2017.

Aged 21, he was at the helm of a protest that proved a lightning rod for criticism last weekend, as video footage showed he and other demonstrators shouting, “Drag queens are not for kids,” and police later being called.

Demonstration detractors denounced Gavin and thew Liberal National Club, with one witness saying: “What they did today was add to the bigotry, division and trauma young children are left to face in today’s society.”
