A "sealed suitcase" has found itself at the centre of a complaint against Union Minister Dharmendra Pradhan who allegedly misbehaved with government officers in Odisha trying to conduct checks amid the ongoing Lok Sabha elections. The ruling Biju Janata Dal (BJD) on Wednesday wrote to the state Chief Electoral Officer demanding action against the petroleum minister, days after the Congress asked the Election Commission to look into a "mysterious box" that was moved from Prime Minister Narendra Modi's helicopter to his car when he was campaigning in Karnataka last week.
