Three girl students of Class 3 were allegedly sexually assaulted by an outsider in the library of a private school here, police said Thursday.
Angry parents protested outside the school in west Delhi's Chhawla area Thursday alleging that their daughters were sexually assaulted by a book seller inside the school's library Tuesday.
Police said they were verifying the allegations.
The school authorities, however, have said that they are not aware of the incident.
