The National Investigation Agency (NIA) will probe the derailments of Indore-Patna Express in Kanpur last year and Hirakund Express in Andhra Pradesh last week.
One hundred and forty-eight were killed and 200 injured in the Kanpur accident, while 39 died in the Hirakund train tragedy.
“Union home ministry has issued formal orders for a probe by the NIA into these two train derailments,” said NIA spokesperson Alok Mittal.
Besides these two cases, the NIA has also been asked to probe the recovery of an Improvised Explosive Device (IED) on Raxual-Sitamarhi railway track near Ghorasahan in Bihar on October 1, 2016, Mittal added.
In the Ghorasahan case, the NIA registered an FIR on Wednesday and is in the process of registering two more FIRs in connection with the derailments of the Indore-Patna Express and Hirakund Express trains.
The government is considering sabotage angle in the two derailment cases, following the arrests of Moti Paswan, Umakant Patel and Mukesh Rai by the Bihar police in Ghorasahan case.
One of the suspects — Moti Paswan — told the Bihar Police that his group was behind the derailment of Indore-Patna Express also.
The external intelligence agency too informed the government that a Karachi-based FICN kingpin Shafi Shaikh was in regular touch with Nepali national Shamsul Hoda who in turn hired criminals for subversive activities in India including planting bombs on railway tracks, said sources. Hoda is believed to be in Dubai now.
