The schools which have decided to shut down till Sunday includes Pathways school, GD Goenka School, Shiv Nadar School and Delhi Public School.
The management of the schools confirmed that they would close down as a precaution despite the district administration and the Gurgaon police assuring adequate security.
Around 25 students of GD Goenka World School were on their way home when a group of around 60 activists, believed to be members of a fringe group, attacked the bus with bamboo sticks asking the driver to stop the vehicle.
"We do not want to take any risk with the life of students. Protection of students outside and inside is our prime concern," a school teacher told PTI on the condition of anonymity.
"If the violators can attack school buses and Haryana roadways buses openly despite prohibitory orders and tight security arrangements of the Gurgaon Police," the teacher said, adding, "We cannot take a chance and have decided to close down."
The teacher said that a total of six schools have taken the decision to remain shut.
Gurgaon Deputy Commissioner Vinay Pratap Singh, in an appeal, said the public transport system of the city should not be disturbed.
"Everyone has the right to protest but in a peaceful way.
Violation of law and order is not allowed. The situation is peaceful in Gurgaon and all colleges, schools, offices will remain open on Thursday," he added.
