Rajkot: A 25-year-old man was booked for raping his minor cousin around six months ago and impregnating her. Based on a complaint filed by the survivor’s mother, Aji Dam police booked the acused Sanjay (name changed), a resident of Kothariya Road, on Friday night. According to police, the family of the girl came to know about the incident only after a medical check-up revealed that she was five months pregnant. The 17-year-old Class XII student was allegedly blackmailed by her cousin to concede to his sexual demands around six months ago after he threatened to expose her affair with one of his friends. The survivor, only child of a middle class family, had met him at accused Sanjay’s wedding last year and got romantically involved over a period of time, which Sanjay came to know. He, however, used the information to his own devilish designs and threatened his cousin of revealing the duo’s chat conversations to her parents if she did not meet his demands. Fearing that Sanjay, who works in a finance company, would tell her parents about Sameer, the survivor remained silent. Taking advantage of this, Sanjay took her to different places near her home and raped her repeatedly, asking her not to tell anyone about it. However, her mother started noticing recently that her daughter’s stomach had started to bloat abnormally and confronted her about it. The girl broke down and revealed her ordeal to her mother who then took her for medical examination where to their horror found out that she was pregnant. “We have registered an offence and will arrest the accused soon. Since he saw the messages on his friend’s phone and took photos of it to threaten the girl,” said inspector V J Chavda.
