The incident took place 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 from Chhindwara 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.
