Lok Sabha MP P Mithun Reddy went to the cabin of AI manager at the airport Rajasekhar yesterday afternoon and picked up an "argument" with him regarding boarding passes for his relatives for a flight.
He later "shouted" at the manager before allegedly slapping him, Yerpedu police station sub-inspector Ramakrishnaiah said based on a complaint lodged by the victim.
Following the complaint, a case was registered last night against the MP along with his 15 other followers under sections 323 (voluntarily causing hurt), 353 (assault or criminal force to deter public servant from discharge of his duty) and 448 (house-trespass) of IPC, he said.
"We are investigating the matter," the SI told PTI over phone.
Some passengers, who were to board the flight, had also complained to the MP that the manager had allegedly misbehaved with them, after which Reddy went to Rajasekhar's cabin.
Mithun Reddy represents Rajampet constituency in Kadapa district of the state.
