A 25-year-old man, Keshav, allegedly stabbed his entire family to death in southwest Delhi's Palam area on Tuesday night, just a few days after returning from a rehabilitation center, police said on Wednesday.
Following some alleged altercations, Keshav murdered his parents, 18-year-old sister, and 75-year-old grandmother using a sharp object to attack them multiple times before slitting their throats.
Sharing the details of the crime, Delhi Police officials said they received a call from Keshav’s relatives, who lived in the same building around 10:30 pm on Tuesday about a quarrel on the first floor in the Palam area.
Later on, Keshav's relatives caught him while he was trying to flee and handed him over to the police.
Police have also said a preliminary investigation suggests that Keshav was under the influence of drugs at the time of the crime. Meanwhile, the bodies of the family have been sent for autopsy for further details.
