Vikas Sinha, an associate of former Jharkhand Chief Minister Madhu Koda, was on Friday arrested by the Enforcement Directorate in Ranchi for his alleged role in carrying out hawala transactions and illegal investments.
Sinha, brother of another associate Binod Sinha, will be produced before a local court, where the ED will seek his police remand before he is sent to the Directorate's regional headquarters in Patna.
Sources in the ED said he is allegedly involved in investing and routing Koda's money through hawala channels.
Sinha, who was arrested when he appeared before the ED, is the first associate of Koda to be taken into custody by the Directorate, among the eight people it has summoned for questioning in the multi-crore scam.
