The 18-year-old activist who organized a Gay Pride march in Changsha, China has been detained by police.

According to the AP, the teen, identified only by his surname Xiang, was taken into custody following Friday's protest. He has been ordered to serve 12 days in a detention center.

Officials have charged the teen with organizing an illegal march. Street demonstrations in China require a permit, but few are allowed to proceed.

Roughly 80 activists joined in the march, carrying a giant rainbow flag in support of the International Day Against Homophobia and Transphobia (IDAHO) along a riverfront park. IDAHO marks the 1990 date homosexuality was removed from the World Health Organization's (WHO) International Classifications of Diseases.

On the group's website,, the organizers stated their hope that the protest would “write a new chapter in the struggle for equal rights for [gay] comrades.”
