Jharkhand Chief Minister Hemant Soren's whereabouts created a great concern in the offices of the Enforcement Directorate today as the agency went to his Delhi residence for a search. Mr Soren was not at home and the agency, after conducting a search, seized some documents and his BMW car that they claimed were bought using illegal funds. But the officials, who wanted to record Mr Soren's statement, were left in the dark on his whereabouts. So far, the Chief Minister has evaded seven summons for questioning and sources said he is prepping to challenge the ED's summons in court.
