Four attackers fired at the two securitymen in a DMU passenger train at about 11 PM last night, Railways SP Jitendra Mishra said today.
While GRP jawan Abhishek Singh, a resident of Narahi village of Uttar Pradesh, died on the spot, his colleague Nand Lal Yadav was grievously injured, the SP said.
The injured jawan informed the GRP Buxar about the incident.
The attackers, who took away two INSAS rifles of the jawans, got down from the train and fled before it reached Buxar.
Meanwhile, Mughalsarai GRP Inspector Tripurari Pandey said the two constables were on escort duty. The incident occurred soon after the train left the Chausa railway station for Buxar.
The criminals also looted cartridges and jumped out of the train when it slowed down, Pandey said.
