CHENNAI: City police commissioner A K Viswanathan is showing that he can walk the talk. When he took office on Monday, the city police chief promised 'citizen-friendly policing'. It's too early to take a call on whether he has kept his word but, four days since then, he has taken action in that direction even if it has been at the expense of his own men who have committed offences or failed to perform their duty. After police on Wednesday arrested sub-inspector Sundaravadivel of the secretariat police, for taking 20kg of ganja to his house from a crime scene, Viswanathan on Friday suspended an inspector for failing to file an FIR on a complaint by a woman who lost her gold chain to robbers.
