CUDDALORE: Sleuths trailing the gang that robbed soiled currency notes worth `5.75 crore off a moving train landed at the Vriddhachalam railway junction to carry out their second phase of investigation on Tuesday.
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. On Monday night, the team began its investigation at Vriddhachalam junction and carried out its work well into Tuesday. They asked the railway employees about the exact location of the particular coach on that day when train was halted here for engine change.
Attempting to figure out all the possibilities of robbery, they measured the distance between the roof of the coach and the electric line that passes above it to find out if a man travelling above the coach could have drilled the hole. Later, the officials drew a map based on their collected data.
The team collected the details and mobile numbers of the railway workers, who were on duty on the day the robbery took place.
Vriddhachalam Deputy Superintendent of Police (DSP) Karthikeyan met the Superintendent of Police and explained about the search operation carried out by his team along the track between Vriddhachalam and Ulundurpet.
CB-CID inspector Deepa was also present during the investigation.
