The teachers had staged the protest under the banner of Azad Adhyapak Sangh on Saturday in Jamboorie Ground in Bhopal, which is owned by the Bharat Heavy Electricals Ltd (BHEL), and both men and women protestors had their heads shaved.
The government drew flak as the issue came to light after the pictures of receipts of rent paid by the Mr Sangh went viral in the social media on Monday.
"There is a fixed charge which one has to pay for holding any programme in the Jamboorie Ground. The Adhyapak Sangh also paid that much only," Public Relations Officer Vinodanand Jha told IANS on Monday.
Condemning the collection of fee from teachers, secretary of the state Communist Party of India-Marxist (CPI-M) Badal Saroj said it was the right of teachers to lodge their protest, and charging fee from them was "strangulation of democracy".
Mr Saroj said the government had failed on all fronts and now it was trying to restrict even protest marches and strikes, he added.
"This type of dictatorship should be stopped. The money collected from the teachers should be returned to them," said the CPI-M leader.
