In an incident that is bound to draw a lot of criticism, DMK treasurer MK Stalin was on Wednesday caught slapping a man onboard the newly-launched Chennai Metro Rail services. As per a video which came to the fore on Thursday, Stalin is seen slapping a man while taking a ride on the Metro. The passenger, reportedly a party worker, who was standing alongside Stalin, was then asked to move from there. The DMK has denied the charges against Stalin, saying he just gestured to the man to move away from women who were sitting. However, Tamil Nadu Chief Minister Jayalalithaa has condemned the incident.
