What does the law say about 'fake fielding' which Virat Kohli is accused of doing?

During Bangladesh's seventh over, Virat Kohli mimed a throw at non-striker's end despite not having the ball. As per cricket laws, it's unfair for fielders wilfully to attempt, by word or action, to distract, deceive or obstruct batters after striker has received the ball. Further, it's for umpires to decide whether any distraction, deception or obstruction is wilful or not.
