Muktar Hossain, 54, was working as a constable at Madaripur.
Kamrul Hossain, officer-in-charge of Madaripur Sadar Police Station, said the constable has been residing with his wife in rented accommodation in TB Clinic area of the town for a long period. He called the 16-year-old girl in absence of his wife and violated her at 8 pm on Sunday.

Later, the constable was withdrawn and attached to the nearest police lines as the news spread.
Besides, a probe body has been formed to look into the matter headed by Badrul Alam Mollah, additional superintendent of police, Madaripur Sadar Circle.
