Hemant Soren, the de-facto chief of the JMM, was arrested by the ED on Wednesday night after nearly seven hours of questioning on money laundering charges in an alleged land fraud case.
Earlier in the day, Champai Soren along with 43 legislators had met Jharkhand Governor CP Radhakrishnan at Raj Bhavan, staking claim to form the government in the state.
Hemant Soren was untraceable on Monday after Enforcement Directorate officials, who had arrived at his Delhi residence for questioning in a land fraud case, failed to locate him for nearly 30 hours.
