A 14-year-old mentally challenged girl was allegedly raped by her brother-in-law for over six months in Durga slum area near here, police said on Saturdayday.
The incident came to light yesterday when the girl's neighbours caught the 45-year-old accused red-handed and handed him over to police, Jawahar Nagar police station SHO Bhanwar Singh said.
The accused, Dev Kumar Mandal (45), used to visit the girl's house regularly and rape her whenever he would find her alone.
Most of the time the victim was alone at home as her mother, who is also mentally challenged, was at her paternal home in West Bengal while her father, a labourer was away on work.
The teenage victim said in her statement to the police that the accused had threatened to kill her if she revealed the incident to any one.
