The Johor Education Department has completed an internal investigation into an alleged racially-motivated attack on a teacher at a Johor Chinese primary school for the Education Ministry.

"We've sent the report," Johor Education Department director Aminudin Amin told Malaysiakini , although he could not recall when the report was sent.

Education Minister Mahdzir Khalid said the action to be taken against the headmistress of SJKC Pai Chee in Mersing was yet to be determined.
