A fast track court in Alipore on Friday sentenced Ranjit Ghosh to 10 years in prison for raping a 20-year-old girl in 2005.
Police said Ghosh had sexually exploited the girl by promising to marry her but refused when she gave birth to a boy.
Senior additional public prosecutor Md. Baddruddin said a DNA test confirmed that Ghosh is the boy’s father.
But he still refused to marry the girl, following which she lodged a complaint of rape against Ghosh.
He was arrested but was out on bail till his conviction.
