Updated at 5.13pm: A secondary teacher in Mongkok was arrested for throwing egg tarts at a colleague during a row over food, local media reported on Friday. The 46-year-old woman teacher at the Sir Ellis Kadoorie Secondary school sent cakes and pastries to some 60 people having a seminar in the school's library on Friday morning. But a male teacher declined the offer and complained to the principal saying food was not allowed in the library. An egg tart was thrown at the male teacher during the dispute. The woman teacher claimed she was being careless and apologised for it. But this was not accepted by the male teacher who said it was not sincere. The pair continued to quarrel until Friday afternoon when the male teacher called police. Police had to arrest the woman teacher after attempts at reconciliation between them failed.
