A 25-year-old woman and her four-year-old son were strangled by her live-in partner here in the capital, police said Sunday.
Rukhsana and her son Firoz were found dead in their rented accommodation in a slum in north Delhi's Sarai Rohilla area around 8 a.m. Sunday.
Her sister Naveesha told police she found their bodies when she entered the house.
Police said Rukhsana's live-in partner Salman committed the crime Saturday night and fled after locking the door of the house from outside.
"A hunt is on to nab Salman," said a police official.
Rukhsana, who hailed from Bihar, had been staying in Sarai Rohilla along with Salman for around three months.
Salman, who works in a private factory, hails from Uttar Pradesh and became friends with Rukhsana five months ago.
"Rukhsana and Salman used to fight over petty issues. They were involved in a heated argument Saturday night, but the situation became normal after the interference of their neighbours," the official said.
Rukhsana got married four years ago but her husband recently went to Nepal after marrying another woman.
