A day after a group of unidentified robbers managed to sneak into a coach in a running train in Tamil Nadu and decamped with Rs 5.78 crore, a probe into the matter has suggested that it may be an insider’s job.
The Tamil Nadu Police, which swing into action, have now called several bank employees for questioning in connection with the case.
Those who have been called for questioning belong to the Indian Overseas Bank, SBI and other public sector banks.
Meanwhile, an RBI official said the train was also carrying soiled notes.
“Out of the 226 wooden boxes, four boxes were found tampered with soon after the train reached Chennai to Salem,” said the officials.
Police have widened their search from the originating point – Erode from where the rakes of the train came – and also were looking at the CCTV footage of all the 10 stations between Salem and Egmore in Chennai where the train terminated.
“We are investigating Erode yard from where the train rake originated, if the hole could have been cut there. We have also questioned the porters who loaded the train and also checking with the bank staff about the people who had information about the money being transported,” said P. Rajmohan, divisional security commissioner, RPF, Salem Railway Division.
The money was loaded in the train in afternoon when the Salem Express was in its yard.
“We are looking at the case from the originating point – the banks in Salem, their staff,” Rajmohan said.
The forensic department has recovered four pairs of fingerprints and a blood sample from the crime scene, said sources.
The train had stopped at Virudhachalam Junction for an hour for engine change. The train ran on a diesel engine from Salem to Virudhachalam and then the engine was changed to an electric one. Electric engine stretch is from Chennai to Virudhachalam.
Based on the cut on the top of the roof of the train, cops deduced that the robbers had a chance to enter the train when it was between Salem to Virudhachalam, as after that stretch there are high tension wires on the line carrying 25,000 volts and this would make it extremely difficult and risky to conduct such a heist, said sources.
