He said that the incident appears to be a result of "error" on the part of Railways. Manjhi also said that he spoke to Railway Minister Sadananda Gowda about the incident and also drew his attention towards announcement of ex-gratia of Rs 2 lakh for the family of the dead whereas the standard practice is to pay Rs 5 lakh ex-gratia in such cases.
