A shocking video of a college student slapping a Chennai policeman has now gone viral. The student is seen assaulting the policeman in full public view after being stopped for traffic violation. The video shows the student abusing the policeman first and then going on to assault him. Constable Mageswaran was manning the traffic at Pari Nagar-Karikalan Nagar junction last week when he stopped three men on a bike for helmetless riding and triple riding offences. The trio refused to stop and sped away only to fall over a pothole nearby. Enraged, one of the pillion riders, Manikandan, walked up to the constable to pick a fight. Watch this viral video here.
