Hindupur MP Nimmal Kristappa's son Ambarish was on his way to Bengaluru International Airport and was asked to pay the fees at the toll plaza located near the Andhra Pradesh- Karnataka border, police said.
The occupants in the car along with Ambarish showed a pass, saying it exempts them from paying the toll.
This led to arguments between them and toll plaza staff and resulted in ransacking and vandalising of the tollgate, police said.
A counter complaint was filed from Ambarish'sside, accusing the toll plaza staff of damaging their car and obstructing them.
