Gurugram, June 25 -- A three-year-old boy whose body was found with his throat slit in Faridabad's Shiv Durga Vihar on Sunday morning was allegedly murdered by his stepfather, who police said killed the child because he was upset that his wife frequently visited her son from a previous marriage. Police on Wednesday said the accused, 26, a resident of SGM Nagar, Faridabad, was arrested by a crime branch team on Tuesday. Police recovered the alleged murder weapon, a knife, from the residence of the family on Wednesday, officers added. According to investigators, the accused had married the victim's mother about a year ago. "The deceased's mother frequently visited her parental home in Shiv Durga Vihar from SGM Nagar to meet her son from her previous marriage, which used to annoy the accused," Yashpal Yadav, public relations officer of Faridabad police, said. Yadav said the deceased's mother had arrived at her parental home with the accused three days before the incident. Police alleged the accused took advantage of the situation, slit the child's throat with a knife while he was alone in a room, then left the house to avoid suspicion before returning after receiving a call about the incident. An FIR under Section 103(1) was registered at Surajkund police station on the complaint of the boy's maternal grandfather.htc...
