The 33-year-old teacher, who bit a first form school boy of Saraswat Primary School on the pretext that he was inflicting love bites, was released on station bail from the Leonora Police Station.
The police explained that the man had been in custody for the stipulated 72 hours and had to be released.
Yesterday, the Child Protection Agency of the Human Services Ministry explained that efforts were still being made to take a statement from the child so that charges could be instituted.
The statement was expected to be taken yesterday.
Since the incident that occurred on Sunday, the child was removed from the home that he occupied alone with help from two female neighbours and installed at an institution in the city.
Vigilant teachers, on noticing the marks on the child, called in the police who learnt of the sexual assault on the child. They arrested the teacher.
Head master of the school, Esau Dookie, said that the man, an undisguised homosexual, began teaching at the school since 1998.
