Ankit, a resident of Jalaun district, jumped in front of a train near Govindpuri Railway station here yesterday, the GRP said.
However, when the GRP informed about the incident to Ankit's parents, they assumed it to be a prank and ignored the call twice, they said.
GRP officials then sent the body for post-mortem after waiting in vain for four hours.
Later, the information was conveyed to the parents by GRP officials in Jalaun, after which they arrived in Kanpur.
