NEW DELHI, Aug 18 (PTI) : Union minister VK Singh's wife Bharti Singh has filed a police complaint here against a 27-year-old man alleging that he was trying to extort Rs two crore by blackmailing her with "doctored" audio-video clips to defame her husband.

In her complaint lodged at Tughlaq Road police station, Singh alleged that Pradeep Chauhan, a resident of Gurgaon, had even threatened her of "dire consequences" if the money was not paid.

The accused allegedly called her several times and threatened to "ruin" her husband's reputation. He allegedly called repeatedly on the night of August 6.

A minister's wife getting black mailed. That is interesting. Only a proper investigation would bring out the truth.

She also expressed "grave threat" to her security alleging that Pradeep was a "dangerous" man who carried guns.
