Lalitpur (Uttar Pradesh), Feb 26 (IANS): The family of Aam Aadmi Party's Uttar Pradesh co-in charge Murari Jain, 61, who was found dead under mysterious circumstances on Monday, has now demanded a high-level inquiry into the death.

Deepak Jain, the nephew of Murari Jain, said the AAP leader was returning home in the Pushpak Express after attending a party programme in Lucknow.

He said his younger brother Vivek received a phone call from his uncle saying that he could not deboard at Lalitpur as he was feeling sleepy and would disembark either at Bina or Bhopal in Madhya Pradesh.

Deepak Jain said his uncle also told Vivek that the train was passing over the Narayani river -- the same spot where his body was found the next day.

When Vivek called up again his uncle after half an hour the latter's mobile phone was switched off.

Jain's body was found on the riverbed under the railway bridge in a forest area. A small bag with clothes in it, his mobile phone and some documents were lying nearby. There were fractures in both the legs as if he had suffered injuries after falling from the bridge. There were injuries in the head and other parts of the body also.

Meanwhile, the body was handed over to his family.

The post-mortem report is still awaited.

Jain's nephew Deepak said, "We want a high-level inquiry as the body has been found in mysterious circumstances. It could be a case of murder."
