A Delhi Police inspector was arrested along with an accomplice for allegedly seeking a bribe of Rs 30 lakh from a complainant for doing her a "favour" during the investigation of her case, the police said Tuesday.

The two accused were subsequently sent to police custody for a day.

The Delhi Police's vigilance unit cracked down on the accused, Jitendra Singh Yadav, Inspector (Investigation), Greater Kailash police station, after one of his accomplices, Dharamveer, was caught red-handed while accepting Rs 1 lakh from the complainant, officers said. Dharamveer was allegedly posing as Yadav's lawyer and moving the cash on his behalf.

The complainant approached the vigilance unit on Monday, stating that a First Information Report (FIR) was registered against her and her husband at the Greater Kailash police station.

According to Anyesh Roy, Deputy Commissioner of Police (DCP), Vigilance, the complainant said that Yadav, the investigating officer (IO), demanded a bribe from her for doing them a "favour" in the case. "After bargaining, the bribe amount was settled at Rs 30 lakh. The complainant further said that Inspector Yadav directed her to pay the bribe amount to Dharamveer, who presented himself as an advocate," the DCP said.

A team led by the Assistant Commissioner of Police, Vigilance, was formed on Monday, and a trap was laid, officers said, adding that Dharamveer accepted the bribe from the complainant on Yadav's behalf. As soon as the cash changed hands, the police nabbed Dharmveer.

"Later investigation revealed that Dharamveer is not a registered legal practitioner and was falsely presenting himself as an advocate. After completing all procedures, an FIR was registered at the vigilance police station under provisions of the Prevention of Corruption Act, and the Bharatiya Nyaya Sanhita (BNS). Inspector Yadav and Dharamveer were arrested and are now in police remand," DCP Roy said.
