The president of the Education University, Stephen Cheung, said on Friday that his staff were working to track down those responsible for putting up a poster containing an offensive comment about a government official whose son died this week.
Cheung said two perpetrators had been captured on CCTV putting the poster on a notice board at the university's Tai Po campus, but their identities weren't known and it wasn't clear if they were students.
The poster on the university's "democracy wall", which is managed by the student union, “congratulated” Undersecretary for Education Christine Choi on the death of her son on Thursday.
Peter Poon, 25, jumped to his death from a flat above Kowloon MTR Station.
Cheung said he was very angry and upset about the poster incident and he apologised to Choi and her family on behalf of the university.
"We allow freedom of speech, but we expect them [the university's students] to mutually respect each other. This is my bottom line," he said.
Cheung said investigations were continuing and a disciplinary committee would decide what to do with those responsible if they are caught and are indeed students at the university.
He also rejected a claim by the leader of the student union that the institution was creating "white terror" by tracking down those responsible. Cheung said he respected freedom of speech, but students must also respect other people’s feelings.
The chairman of the university's council, Frederick Ma, said he backs the university president's actions.
As for the poster, he said the public should judge if it crossed the line. “I would like Hong Kong people to answer one question. If you were parents, would you like your children to be educated by people like this?” he asked.
Other posters, including some advocating Hong Kong independence, have appeared at several universities this week, sparking confrontations between local and mainland students.
