LUCKNOW, Nov. 11 -- A Shahjahanpur businessman allegedly strangled his wife to death and attempted to kill their 11-year-old daughter during a domestic assault around 1am on Tuesday. Their 16-year-old elder daughter escaped by locking herself inside a room and alerted her paternal uncle over the phone. Seema (40) died during treatment at the medical college, while her younger daughter, Anjali (11), remains critical in the intensive care unit (ICU). Additional SP (City) Devendra Singh said the accused, Kamlesh, was allegedly under the influence of alcohol when he attacked his family. "He strangled his wife and attempted to kill his daughter by strangling her. The accused has been arrested and is being questioned," he said. The incident took place in the Roza police station area, around 10 km from the district headquarters. Police said Kamlesh, who runs an electronics shop, had been facing financial difficulties and was burdened with debts running into lakhs of rupees. A quarrel reportedly broke out between him and Seema over his business problems around 12.30am, following which he allegedly attacked her. Hearing her mother's screams, Anjali rushed to intervene but was also assaulted. Kamlesh then turned towards his elder daughter, Komal alias Ananya, who locked herself inside a room and called her uncle. He alerted the police, who rushed the injured woman and child to the medical college. Kamlesh was arrested from the house. The accused's father, Ramesh Chandra Gupta, said the family had never noticed any serious dispute between the couple. Seema's brother, Ashok, said he had spoken to her on Monday evening, but she had not mentioned any trouble at home. Police are investigating the circumstances leading to the attack....
