The Hong Kong Polytechnic University has been quoted as saying that it will keep ripping down pro-independence material on campus "to prevent students from potentially violating the law".
The university's management held talks with members of the student organisation, Poly U Pavilion, on Monday morning. They discussed the recent removal of material from the "democracy wall" notice board managed by the students union.
A former president of the union, Franco Wong, quoted the institution as saying that it plans to keep tearing down any pro-independence material it finds.
Another student at the meeting, Ruben Angulo-Chow, accused the uni of suppressing free speech.
Angulo-Chow said the group plans to launch a joint campaign with students from other universities to fight for freedom of speech, arguing that the suppression isn't an isolated incident.
"Hong Kong independence" banners and posters have appeared at all of the city's public universities since the start of the current academic year. The heads of the institutions issued a joint statement this month making it clear they do not back calls for the territory to break away from China.
