CHENNAI:With no clue yet even 50 hours after the daring theft of Rs 5.75 crore from an express train, enquiries are now confined to 30 persons from different institutions involved in the process of transferring the currencies.
The investigators are questioning the staff and officials of the banks, railways and the police, involved in the process.
The CB-CID, which took over the probe on Wednesday, has appointed Deputy Superintendent of Police Sevanupandi as the investigation officer in the case. Superintendent of police G Nagajothi will supervise the probe.
Police hope the CCTV footages of the Salem Express, as it crossed specific stations, would provide the vital clues. While reports suggested that a CCTV footage of the train recorded at Tambaram did not show any hole in the roof of the compartment, police have refused to confirm it. However, a senior police officer said this angle is also being investigated.
If true, this could mean that the thieves had made away with the loot either at the Egmore railway station or the Chetpet yard, where the train was stationed for nearly six hours, before the theft came to light.
While a few reports suggested that pieces of the wooden boxes was found along the tracks at Virudhachalam, police denied such a development. Karan Singha,ADGP, CB-CID visited the station on Wednesday.
