Representative image KOLKATA: CID, which had started a parallel investigation into the multi-crore coal scam, made its first arrest on Friday night. The state probe agency arrested businessman Randhir Singh from Andal in West Burdwan after questioning several ECL employees from Durgapur and Asansol-Raniganj coal belt through the week. Confirming the arrest, DIC (operations) Ajoy Thakur said the complaint was filed by ECL authorities in 2020. He, however, refused to share more details saying the matter was under investigation. Sources said more arrests were likely. Singh's arrest is being seen as important since he is considered a close aide of multi-crore coal scam prime accused Arup Majhi alias Lala, who has not responded to several CBI efforts to question him. A lookout notice has been issued against him. The enforcement directorate is also investigating the case.
