A LECTURER accused of sexually harassing his students has told the South China Morning Post he recalled patting the women's shoulders but was unsure whether he had reached for their legs and waists. 'Patting shoulders, I can confirm this. Hands or backs, possible. Legs and waists, I am not sure,' the Polytechnic University lecturer said. 'I have apologised to the students in class but there was no response. But apologising doesn't mean I admit I am guilty.' The lecturer has been banned from teaching the class involved and police are interviewing 50 students in his other classes. Nine students from a class of 17 in the Department of Chinese and Bilingual Studies have accused the man of touching their waists, shoulders, backs, hands and legs. The university is also investigating the case. The lecturer involved, who cannot be named for legal reasons, has defended himself. '[The accusation] is unfair. Nothing like this has happened over the last two years. But suddenly I was told I was wrong,' he told the Post earlier. He said he apologised for making the students uncomfortable and his acts were only meant to be friendly gestures. It is understood the students cancelled a meeting they were to have yesterday with the lecturer and the department staff. The lecturer has said he wanted to talk to the students in order to solve the problems in the most effective way. A police spokesman said it was difficult to determine whether the evidence constituted indecent assault. 'No important parts of the body were claimed to be touched. It is difficult to define whether the acts are intentional or just friendly gestures,' he said.
