A woman and her one-and-a-half-year were allegedly stabbed to death by her husband in Delhi's Jahangirpur area late last night.
The accused Omprakash, reportedly killed his wife, Sobha and his son in front of his two other children and then ran away from the spot.
"Husband is under suspicion, as he is absconding. A case has been registered under section 302 of the India Penal code (IPC)," said DCP North, Aslam Khan.
Meanwhile, woman's brother also accused Omprakash of assaulting his sister.
The police have sent both the bodies for postmortem and are further investigating the matter.
