In an interview with Dot Dot News, Lee Cheuk-hing issued a public apology over the incident.
He said as a school leader, he should have led by example and exercised restraint under all circumstances.
Lee added that he will fully cooperate with all arrangements and investigations by the school’s governing body and the Education Bureau.
He was suspended earlier this week after an online video purportedly showed him swearing at a security officer.
The incorporated management committee of San Wui Commercial Society Secondary School said Lee submitted his resignation on Thursday.
Former lawmaker Edmund Wong, who is an independent manager of the committee, stressed that the welfare of students is their top priority.
He said the committee will hold a meeting in the next one or two days to decide whether to accept Lee’s resignation.
“There are various factors to be considered whether to accept the request to resign, such as whether school operations will be significantly affected, and whether the decision meets the expectations of students and parents,” he said.
Wong added that an internal probe is still under way and a report will be submitted to the Education Bureau once the investigation is concluded.
Meanwhile, the Home Affairs Department said Lee has offered to step down from his positions on the Tuen Mun Northwest Area Committee and a care team.
