The Powai police have booked a 20-year-old for sodomising two minors, and the two minors in turn have been booked for sexually assaulting three children inside the campus of a reputable educational institution.

The police said all the victims and accused are children of labourers working at a construction site on the campus. All the children involved were part of the day-care centre on the premises and the incident came to light when the caretaker overheard the three children discuss the abuse among themselves.
