Three girls of Kasturba Gandhi Balika Vidyalaya (KGBV), a residential school at Kotturu under Anatagiri police station limits in the Agency area of the district, were reported missing.
Though the minor girls went missing on January 23, it came to light only on Friday after the parents of the girls lodged a complaint with the Anantagiri police.
While one of the missing girls is a student of Class 10, the other two were from Class 8.
They reportedly went home for holidays, located in the same mandal, but did not return to the school after it reopened.
The parents who came to the school found that their children had not come to school, according to reports reaching here.
Anantagiri police formed a team to trace the girls.
