Real estate firm DB Realty, embroiled in the 2G spectrum allocation case, has moved the Delhi high court for vacation of a Rs 223 crore attachment order of the Enforcement Directorate against it under money laundering laws. The Delhi HC has now issued a notice to the ED on the writ petition filed by the firm and their associates. The agency had attached immovable properties and bank accounts of the firm in January this year under the stringent provisions of the Prevention of Money Laundering Act in connection with its probe into the alleged bribe of Rs 200 crore paid to Kalaignar TV.
