New Delhi, Jun 25: Railway today suspected “sabotage” by maoists behind the derailment of Delhi-Dibrugarh Rajdhani Express at Golden Ganj station near Chapra in Bihar as there was a blast on the track.

“Prima facie, it appears to be a case of sabotage. There was a blast on the track, which could have caused the derailment,” Railway Board Chairman Arunendra Kumar told PTI.

“Another goods train, 60 kms away from the station, also got derailed due to a blast. At least four people were killed and eight injured after nine out of twelve bogies of Delhi-Dibrugarh Rajdhani Express train derailed in Bihar’s Saran district early on Wednesday, police said.
