A Delhi-based freelance journalist, Aparna Kalra, is battling for her life at Fortis Hospital after she was brutally attacked by an unidentified person on Wednesday.

Kalra, 45, was out for her evening walk in a park near her home in northwest Delhi's Ashok Vihar when she was attacked.

Kalra, who suffered multiple brain injuries, gained consciousness briefly on Wednesday night, but fell unconscious soon afterwards. During the brief period that she was conscious, she managed to tell the police that she was attacked.

Aparna Kalra's uncle HC Bhatia told Hindustan Times that she has undergone surgery and also revealed that some part of her skull is missing. "She is critical as she has received multiple injuries to her brain nerves," Bhatia told HT.
