A woman allegedly killed her six-month-old son by smothering him with a pillow over financial constraints since both of them had tested positive for HIV, a police official said on Friday, reported the PTI.

The incident came to light on Thursday evening, when the accused woman, who was working at a garment unit at Govandi, had a scuffle with her colleague and had pulled out a knife to attack the latter, he said.

"A police team rushed there after being alerted about the scuffle. While being questioned, the woman told police that the 43-year-old woman had killed her six-month-old son as she was unable to raise him due to her poor financial condition. The woman said she and her son had tested HIV positive," the official said, according to the PTI.
