Two four-year-olds were allegedly sexually assaulted at a reputed school in Thane last week. The local police refused to file an FIR until the District Women and Child Welfare Department got involved. A case was registered under the POCSO Act. A crowd descended on the Badlapur railway station to protest against the sexual assault of two nursery students on August 20. They demanded the harshest punishment for the 24-year-old accused who was arrested on Saturday.
