The headmaster was on leave so some teachers accepted on his behalf copies of the police reports made by two students. The reports also alleged that the teacher had beaten some students.
Coalition of Malaysian Indian NGOs secretary Gunaraj George, who was among those who handed over the reports, said such abuse would only result in breeding hatred and racial polarisation in schools.
Deputy Education Minister Wee Ka Siong said the teacher might be sacked if the allegations were proved true. He added that the ministry was awaiting an official report.
Ethnic Indians constitute eight percent of Malaysia's 28 million population.
