A 57-year-old man allegedly killed his wife over the issue of selling of their flat in south Delhi's Saket area, police said on Saturday.
The incident took place on Friday and police received the PCR call at 7.09 pm, they said.
The victim, Shashi Lata Pandey (52), was found lying on the floor inside the bedroom of their first floor house with no visible injury on her body, police said.
According to police, the caller said that around 6 pm his aunt called him and asked him to come on the first floor when she lived.
He immediately rushed there and knocked on the door, a senior police officer said.
His uncle Chander Mohan Pandey opened the door in clothes soaked in blood and there was a deep cut on his left side of neck, Deputy Commissioner of Police (south) Benita Mary Jaiker said.
Chander asked him to call police saying that “it's all over”.
The man called the ambulance and, in the meantime, his cousin, the son of his aunt, also reached there from Okhla as he had also received a call from his mother, the DCP said.
The ambulance doctor checked his on the victim and declared her dead.
