Calcutta/Sydney: Annoyed by crowd taunts, Virat Kohli Wednesday showed his middle finger to a section of the crowd at the SCG during the second Test and may face a disciplinary action for the gesture.

As Indian bowlers struggled to contain Australian captain Michael Clarke (251 not out) and Ricky Ponting (134) during the course of their 288-run stand, Kohli was photographed raising his middle finger towards the spectators.

Kohli, however, justified his act on Twitter after the second day’s play.

“i agree cricketers dont have to retaliate. what when the crowd says the worst things about your mother and sister. the worst ive heard,” tweeted Kohli. Kevin Pietersen replied, tweeting, “ha ha ha ha ha!!! Welcome to Australia buddy!!”

Kohli responded to Pietersen, saying: “never heard crap like that. EVER.”

Kohli may be charged with Level 1 of the ICC’s Code of Conduct relating to “using language or gesture(s) that is seriously obscene, seriously offensive or of a seriously insulting nature to another player, player support personnel, umpire, match referee or any other third person during an international match”.

However, Match Referee Ranjan Madugalle hasn’t summoned Kohli for a hearing, an ICC spokesman confirmed.
