New Delhi: A special team launched to investigate the great train robbery that took place on Wednesday in Chennai said that the robbery happened because of the information leak by an insider.
Police said a skilled worker could have done the robbery with the help of someone inside the department who knew about the money transfer.
All inspectors between Chennai and Salem who come under Railway Police Force were asked to start the investigation immediately.
A finger print of one of the robbers and few blood marks were discovered on the rooftop of the train, which means one person who was involved in the robbery may have been injured.
A train carrying 228 boxes of old currency notes meant to be transferred to Reserve Bank of India (RBI) was robbed on Monday night. The train was going from Salem to Chennai when the money was robbed.
The robbers entered the coach after cutting through the roof sometime during Monday night or early on Tuesday when the train reached Virudhachalam.
According to the police, approximately Rs 340 crore was being transported in 220 cartons kept in two compartments of the train.
When the train arrived at Egmore station on Monday, it was discovered that two boxes were tampered with, police said. They suspect that few lakhs of rupees could have been burgled.
