THANE, July 22 -- A seven-year-old boy is in critical condition after he was allegedly assaulted by his mother's live-in partner at their rented home in Ambernath on Friday. According to the police, the boy's mother recently separated from her husband and moved to Ambernath with her youngest son, while her two elder children stayed with their father. She began working at an electronics shop and later entered into a relationship with Vikas Singh, an acquaintance of her brother-in-law. The couple started living together. Police said Singh allegedly resented the child, whom he viewed as a hurdle in their intimacy. He had reportedly asked the woman to keep the boy away at night and had assaulted him on earlier occasions. On Friday, while the woman was at work, Singh allegedly beat the child with a rolling pin and repeatedly punched him in the chest, abdomen and groin. When the mother returned home, she found her son's face swollen. When she helped him in the washroom, she noticed severe swelling to his genitals and bruises across his body. Doctors said that the child had suffered a blood clot in his brain, caused by a blow to the head with a rolling pin. The woman confronted Singh on Monday, when he admitted to assaulting the boy, saying he wanted to "get rid of him."...
