The constable was overpowered by Nath’s bodyguards.
The incident occurred at an airstrip in Chhindwara when Nath was about to board a chartered plane for Delhi, additional superintendent of police Neeraj Soni said.
Ratnesh Pawar allegedly took aim at Nath with his service rifle but the security guards of the nine-time MP promptly overpowered him.
Nath, in the meantime, had boarded the aircraft.
Pawar was suspended and SP (city) asked to conduct an inquiry into the incident, Soni said.
