SALEM: A Dindigul-based mimicry artist was arrested late on Monday evening by the Mettur police in Salem district for mimicking the voice of Tamil Nadu electricity minister P Thangamani to transfer officials from one place to another in a Thermal power unit. Police suspect a larger group to be involved in the case.Based on a tip off, the Mettur police initiated an inquiry a few days ago. One month ago, assistant engineer Jayakumar was transferred from the power production unit to the coal handling section. The state electricity minister had apparently contacted higher officials in the thermal unit to execute the transfer.Meanwhile, Jayakumar was placed under suspension a week ago for not performing his duties properly. “He was advised by higher officials to approach the minister to cancel the suspension order,” the police said. When Jayakumar approached the minister on Sunday, he found out that the minister had not made any calls to the thermal plant in connection with his transfer.Realising that something was amiss, Thangamani ordered officials of the thermal power plant unit to probe the issue. The officials in turn sought the help of the Mettur police to nab the culprits.Based on their complaint, the police started examining the call details from the mobile phones of officials. They soon found that mimicry artist Savari Muthu from Dindigul had contacted one of the officials in the unit. “He mimicked the minister’s voice and ordered the transfer of Jayakumar. He had also ordered the transfer of 28 other employees working in the unit over the last few months,” the police said.Following his confession statement, the police arrested Savari Muthu late on Monday evening. The police were clueless about why these people had been transferred.A case was registered and further investigations were on.
