Bhubaneswar: The CBI on Monday arrested Odisha Congress youth wing president Rajat Choudhury and lawyer Debasish Panda in connection with the Artha Tatwa Group chit fund scam. The Central Bureau of Investigation arrested the duo after an hour-long questioning regarding their role in the scam, CBI sources said. The central agency earlier on Monday questioned AT Group chief Pradip Sethy at the Jharpada special jail here. Rajat was quizzed for the fourth time in connection with a land deal with the chit fund firm. He was questioned for two consecutive days on his alleged links with the AT Group in April. Panda, a former lawyer of the Enforcement Directorate, was accused of links with Sethy. Meanwhile, Youth Congress workers protested in front of the CBI office over Rajat's arrest.
