The Sports Authority of India (SAI) took action after the girls spoke out during an U-19 training camp in Lucknow from April 30 to May 25.
The girls, who are preparing for the Asian Junior Wrestling Championship in Kazakhstan, filed a complaint with Sports Minister Ajay Maken on May 16. The matter is now being investigated by a three-member SAI committee.
The complaint states that a coach from Haryana forcibly entered the room of a junior wrestler, who hails from the same state on May 15.
The girl raised an alarm and the other girls reached her room. The coach allegedly got abusive with the girls and threatened them against reporting the matter.
