CB-CID police have detained at the Salem yard five parcel workers who had disappeared after the heist in which Rs 5.75 crore was taken away from a train from Salem to Chennai on August 9.
A team led by CB-CID superintendent of police V Nagajothi has been interogetting them at an undisclosed place, reports, said, quoting sources.
“We have taken their statements and call details to see if match their accounts with their locations at the time of the incident,” a police officer was quoted as saying.
Meanwhile, the Crime Branch CID investigating into the train heist case have sought the details of all the passengers who travelled in the reserved coaches of the Salem-Chennai Egmore Express train on August 8 as part of its probe to look for suspects.
The police have contacted the Salem Railway Division in this regard. The CB-CID also sought the details of the railway staff of the division who were placed under suspension due to negligence of work in the last one year.
A Crime-Branch-Crime Investigation Department (CB-CID) team probing into the heist, wherein a gang drilled a hole on the top of the sealed compartment on Salem-Chennai Egmore Express and decamped with the notes, had last week grilled the station master at the junction.
The team, headed by Superintendent of Police, Organized Crime Unit, CB-CID of Chennai, M V Jayagowri, inquired with the station master and the railway workers.
