The poor boy was subject to the disgusting punishment just because he didn't bring homework back to school. 

'My son was told to lick the toilet 12 times. But after four licks, he vomited,' said the mother of a primary student complained with anger after her son was punished in a disgusting way. 

The astounding incident happened in a primary school in North Sumatra. The poor boy, called by initials MB, was subject to this because he didn't bring his homework to school.  

MB’s mother said they would have found it acceptable if her son was made to clean the toilet but the teacher’s punishment was beyond reason. 'How are there no other punishments?'

However, the school only 'sanctioned' the teacher by transferring her to a public elementary school.
