Rain or shine, there's no stopping when duty calls. A traffic cop in Tamil Nadu's Tuticorin district, who stood amid heavy rain for four hours to manage traffic at one of the busiest roads in the district, has earned huge praise for his persistence. A video of the traffic cop - Constable Muthuraj - performing his duty, undeterred by the downpour, won many hearts on the internet. On Monday, he stood for about four hours in heavy rain to ensure that the traffic movement was not disrupted at the busy VVD junction in the southern city, about 600 km from state capital Chennai.
