Ranchi/IBNS: The Enforcement Directorate (ED) on Friday conducted a raid at Jharkhand Chief Minister Hemant Soren's Delhi residence and seized some documents and his BMW car.

Soren was not at home during the search operations.

The ED claimed to seize Soren's BMW car as the agency claimed it to have been bought using illegal funds.

However, the officials, who wanted to record Soren's statement, were left in the dark on his whereabouts.

So far, the Chief Minister has evaded seven summons for questioning and reports said he is preparing to challenge the ED's summons in court.

The investigating team visited Jharkhand Bhawan and his father's residence at Motilal Nehru Marg. But Soren could not be found there either.

His chartered plane remained parked at the Delhi Airport.

A note from the Chief Minister's Office, however, reached the ED, informing them that they could interrogate him at 1 pm on Jan 31 -- the last day of the time allotted to him -- at his home in Ranchi.

Soren has claimed that he is being targeted as a part of a huge conspiracy.

"A conspiracy was hatched against me, but the final nail in the coffin of the conspirators will be put by us... We will not be scared, your leader will face the bullets first and keep your morale high," Soren had told the workers of his Jharkhand Mukti Morcha.

The case involves "huge racket of illegal change of ownership of land by the mafia" in Jharkhand, as per the central agency.
