Lok Sabha speaker Sumitra Majahan on Friday expressed deep concern over Shiv Sena MP Ravindra Gaikwad brutally assaulting an Air India staffer saying she would ascertain the matter in detail and take action accordingly if there is any complaint.

"The incident happened outside the Parliament, so I will ascertain the details and act on any complaint," Mahajan said outside the Parliament on Shiv Sena MP Ravindra Gaikwad.

"No one is allowed to misbehave with anyone, even if he is an MP, a common man or any official. As a mother, I teach children not to misbehave with people," she added.  

Shiv Sena MP Ravindra Gaikwad was on Friday barred from flying by four private Indian carriers after he assaulted an Air India staffer.

Meanwhile, the Federation of Indian Airlines (FIA) has barred the unruly MP from flying on its member carriers.

IndiGo, too, on Friday said in a statement that it will support any move which bars unruly passengers from flying.
