The incident happened last evening when Aparna Kalra went for a routine walk to Picnic Hut - a popular park in the area which is usually crowded with walkers around that time.
"She went for an evening walk everyday to the park which is two minutes away from her home. She would leave around 6-6.15 PM every day and return around 7 PM before it got dark," her maternal uncle HC Bhatia said.
Yesterday, after leaving for the park at around her usual time, the journalist's family received a call at around 7.30 pm from Deep Chand Hospital and police, saying that she had been brought to the hospital in an injured condition.
On reaching the hospital, the family found her unconscious, severely bleeding from the head and nose. She regained consciousness just long enough to tell police that she had been attacked.
She was later referred to Fortis Hospital, Shalimar Bagh, where she underwent cranial surgery last night.
"She has sustained severe injuries to her brain and skull. She was hit with iron rods and parts of her skull have been reduced to powder," said her uncle.
So far, no eyewitnesses have come forward to share details about the attack and her family members are also clueless about any possible motive, police said.
Robbery doesn't appear to be a motive of the attack since she was neither wearing any jewellery nor carrying her cellphone or any valuable at the time of the attack, police said.
The journalist has been employed with leading dailies and was freelancing for the last year or so.
