"The teenager aged around 16 under the pretext of marrying the girl maintained physical relations with her and after she became pregnant the brothers along with her mother took the victim to a hospital for abortion," police said after a complaint was filed at Wagle Estate Police Station last night.
At the hospital the teenager posed as husband of the girl and approached the doctors, who refused to carry out abortion as the victim was six-months pregnant.
When the victim refused to oblige the teenager threatened her and when nothing worked out refused to marry her, said the complaint.
The duo have been booked under various sections of the IPC.
