The Delhi Police on Wednesday questioned former TERI chief RK Pachauri in connection with the case of sexually harassing a research associate working in his office in February. He was grilled for three hours at his residence in New Delhi district on Wednesday afternoon.

A team from Lodhi Colony police station reached Pachauri’s house number 160 in posh Golf Link Road in New Delhi around 2.30 pm and confronted him with a questionnaire of about 50 queries. Police said the next round of questioning will be held soon.

A case under the Section 354, 354-A, 354-D (molestation, stalking and sexual harassment) of the Indian Penal Code (IPC) was registered against Pachauri on February 18, on the basis of a complaint filed by his former employee of the organisation.

The complainant had claimed that Pachauri had sexually harassed her for nearly two years since she joined the organisation in September 2013. She also alleged that he had engaged in “sexually-laden conversations” with her over email and SMS.

Police said that after getting required approvals from the court, Pachauri was questioned for ascertainment of some facts. Earlier, a trial court on March 21, had granted anticipatory bail to Pachauri while rejecting police’s plea of cancellation of his interim bail.
