The dacoits stopped the train by pulling the chain and robbed passengers of two sleeper coaches and one each of AC2 and AC3 coaches of the Anand Vihar-Bhagalpur weekly superfast train.
It appeared that the gang had around 20 members who forced the passengers to part with their mobile phones, jewellery, cash and other valuables, Deputy Superintendent of Police (Railway), Jamalpur, Shivendra Anubhavi said.
The incident occurred Wednesday night in between Pavail Halt and Daita Dam stretch in Lakhisarai district that falls under Kiul-Jamalpur section, he said.
Anubhavi said the process of working out the total value of the looted articles, including cash, is still on.
"It is in excess of Rs 5 lakh. We are also exploring the naxal angle as the area is Maoist-infested and the modus operandi of the dacoits bears resemblance to that of lower rank ultra-Left guerrillas."
SP (Railway), Jamalpur, Aamir Javed said, nobody was seriously injured though some suffered bruises while the dacoits were trying to snatch away their valuables.
