Hyderabad: Scores of students of Vishwam The Global School at Dilsukhnagar had to return home on Monday as the school was found locked. Parents, who accompanied their wards, couldn't get any satisfactory reply for the sudden closure of the school. There was none to answer their queries. A notice put up at the entrance said there was a holiday for KG and IV classes due to inter-house competitions. However, enquiries revealed that the school, which functions on private premises, was locked out by the owner on Sunday for non payment of rent. "Why should the students suffer on account of the dispute between the school management and the building owner," asked a parent.
