An 86-year-old man and his 80-year-old wife were found murdered, apparently by robbers, at their south Delhi home, police said on Friday.
Manohar Lal Madan, a retired Punjab National Bank employee, and his wife Vimla Madan were found dead at their East of Kailash residence here.
"The couple might have been killed late on Thursday night. Prima facie, it seems the miscreants strangled them," a police official said.
The killers may have been robbers as the house had been ransacked.
Police said the couple were in the national capital to spend Diwali with their eldest son, who was at the first floor of the house when the incident occurred.
The couple's son came down after hearing a commotion and found them dead.
