Lee Cheuk‑hing tendered his resignation on Thursday as principal of San Wui Commercial Society Secondary School in Tuen Mun, school manager Edmund Wong Chun‑sek confirmed.
Wong, a former lawmaker, said the school’s board of directors would have to meet to decide whether to accept the resignation, given the many factors involved.
In a video released later on Thursday, Lee repeatedly apologised for his behaviour to Hongkongers and “all sectors” in Singapore.
“As a principal, I should lead by example. Regardless of the circumstances, I should remain calm and restrained. But unfortunately, I failed to do so,” he said in the clip, which also showed him in tears.
“I admit [my mistake] and apologise to everyone.”
Confirming he had tendered his resignation, Lee also pledged to fully cooperate with investigations by the Education Bureau and the school board.
In an appeal to his students, he said: “Please do not learn from me. At all times, you must try your best to stay calm and resolve [problems] in a rational manner.
