New Delhi: A 15-year-old boy was arrested for allegedly killing his grandmother in a bid to steal money from his house in Delhi, police said on Saturday. The elderly woman was found lying dead on the bed of her house in GTB Enclave on Thursday evening, PTI quoted a police officer as saying. The stolen cash worth Rs 14,000 was recovered from the accused, police added.


The deceased's husband initially did not notice anything suspicious, having thought she died a natural death as he did not spot any external injury on her body. However, when his relatives came over, they pointed out that the woman had an injury mark on the right side of her forehead, police said. 


The elderly man later spotted cash missing from their locker and informed the police. Upon investigation, it was found that the elderly couple's 15-year-old grandson studying in Class 9 had come to the house along with his friend on Thursday, when the victim was alone, the police said.

 When the couple's grandson was questioned, he broke down and confessed to the crime, following which he was apprehended. During interrogation, he told the police he entered the house with his friend with the motive to steal cash. When he found his grandmother lying on the bed, he allegedly smothered her face with a blanket and hit a blunt object on her head. The duo orchestrated the murder in a manner that the death would appear natural, the police said. 


The main accused, who resides with his parents in another house in the same locality, said he needed the cash for personal reasons, they added. The boy's friend, who is also 15-year-old, has been apprehended from the same locality, they added.
