Police yesterday arrested another madrasa principal on charge of attempting to rape a second-grader in Netrakona’s Kendua upazila, just a day after the arrest of a Narayanganj madrasa principal over raping about a dozen female students.

Two separate cases have been filed against a madrasa principal for allegedly raping at least 12 female students of the madrasa in Fatullah area of Narayanganj.

Two minor girls have allegedly been raped, one by her father and another by a neighbour, in Narayanganj and Moulvibazar.
