Police are to hold an internal investigation after a female sergeant accused a male sergeant of sexually harassing her at work by joking about her figure. An officer familiar with the case said the two sergeants, both in their 50s, were instructors at the Police Driving School in Fanling. The woman said she was harassed by the man last week and lodged a complaint with her superior. She had also complained to the Equal Opportunities Commission (EOC), the officer said. The woman said it was unacceptable that she had had to endure such verbal harassment from her colleague. A police spokeswoman confirmed yesterday that the force had received the complaint and said an inquiry would start soon in accordance with procedures. Police said the investigation would be completed as soon as possible and that no one would be suspended from duty. The spokeswoman said the female sergeant would carry on her duties as normal while awaiting the result of the investigation, unless she wished otherwise. The chairman of the Junior Police Officers' Association, Chung Kam-wa, said the union had not received any complaint about the case. Tony Liu Kit-ming, chairman of the Police Inspectors' Association, said there had been fewer and fewer cases of sexual harassment in the force over the past 10 years. Officers were now much more sensitive about such issues, he said, and knew they had to avoid harassment when dealing with colleagues. The force received five complaints about sexual harassment involving police officers in the first half of this year, four in the whole of last year, and five in 2007. An EOC spokeswoman said that for reasons of confidentiality the council would not comment on individual complaints. She encouraged anyone who had felt offended, humiliated or intimidated by any unwelcome sexual behaviour or conduct to lodge a complaint. According to the Sex Discrimination Ordinance, any working environment where people are subjected to actions, language or pictures that are of a sexual nature that make it hard for people to carry out their jobs is regarded as 'a sexually hostile working environment'.
