Kulbhushan Chawla and his wife Kanchan Chawla were sitting on a bench in the park after a stroll at around 9 pm yesterday when unidentified attackers slashed their necks and other body parts with knives and fled before other present could react, a senior police officer said.
The couple's cry for help attracted the attention of those present but the attackers managed to flee.
They were rushed to a nearby hospital where the doctors declared Kanchan dead and her husband was critical, he said.
Their daughter, also married, and Kulbhushan's brother also live in an apartment in the same society apartment.
Police reached the spot after a PCR call and questioned those present at the park at the time of the incident.
Robbery as motive of the attack was doubted as valuables of the couple were not touched.
A case of murder and attempt to murder has been registered at Prashant Vihar police station and investigation has been taken up covering all the angles including property and family related disputes, the officer said.
