A video of schoolchildren cleaning toilets with broom in the Khandwa district of Madhya Pradesh has gone viral on social media.

In the video, students of a primary school in the Sinhara village claimed their headmistress had asked them to clean toilets in return for increasing marks in the examination.

According to sources, since last one year it's the students' responsibility to keep school toilets clean.

However, headmistress Gulab Soni said, "A sweeper cleans the toilets twice a month. Maybe children were cleaning the mud from floor tiles with water."

Education Officer J.L. Raghuvanshi told IANS the project coordinator was looking into it.

A day before, schoolchildren cleaning the mid-day meal utensils with dirty water in the Sagar district had hit the headlines.
