Police on Monday arrested the mother of Delhi-based journalist Nirupama Pathak, who was found dead at her home here, even as it was probing if it was a case of honour killing.

Pathak’s mother, Subha, was arrested on murder charges.

Earlier, Subha and her husband Dharmesh were detained for questioning after the post- mortem report indicated that Nirupama’s death was caused by asphyxia as a result of smothering, Superintendent of Police Kranti Kumar said.

“We have arrested her under Section 302 (murder), 201 (causing disappearance of evidence) and 120 b (criminal conspiracy) of IPC based on circumstantial evidence,” Mr. Kumar said.

Asked whether it was a case of honour killing, the SP said, “The matter is under investigation.”

According to the post-mortem report there was a ligature mark around her neck pointing to strangulation with a rope.

He said the police were misled by the family who had said Nirupama died of electrocution on April 29.

The police were also investigating whether her father, who was a bank employee in Uttar Pradesh’s Gonda district, was at home at the time of the incident.

The parents of the 22-year-old journalist were reportedly opposed to her marrying Priyabhanshu Ranjan, her batch mate at IIMC, who belongs to another caste.
