Hong Kong education authorities have requested a detailed report from a secondary school following complaints that its teachers failed to promptly intervene when four drunk men reportedly harassed two female students during a study tour in Shenzhen.

The incident came to light on Sunday after students from Chang Pui Chung Memorial School revealed it in a post on social media platform Threads.

According to the post, the two Form Five students encountered the men in a hotel corridor one night during the tour while they were on their way to visit their classmates in another room.

The drunk men then approached the girls, tried to talk to them and even filmed them with their phones, the post said. The students then repeatedly called their teachers to seek help, but received no response.

It took around 15 minutes before a teacher from another participating school noticed the situation and stepped in.

Later, a friend of the students reported that a teacher reprimanded the girls for talking to strangers, drawing criticism from some peers who said they felt the girls were being blamed instead of supported.
