NOIDA: A case was registered on Saturday against an unidentified person after a three-year-old girl was sexually abused in a prestigious playgroup school, located in sector 58 Noida, neighbouring New Delhi, police said. 

While the girl, a student of Shemrock Vatika in sector 58, is too traumatized to identify the assailant, she told her mother of the trauma she underwent through gestures, after returning from school on Thursday.
