Within just two months of his taking charge, Karan Singha IPS has been replaced by AK Viswanathan as the Chennai City Police Commissioner. 

This was one among the 17 changes in posts, announced by Niranjan Mardi, the Additional Chief Secretary to the government.

Karan Singha’s transfer comes two months after he took charge. He was appointed after the Election Commission had shunted out S George over allegations of favouritism and bias ahead of the RK Nagar bye-elections.

ADGP Karan Singha has now been posted to the Tamil Nadu Uniformed Services Recruitment Board.

Viswanathan was earlier Additional Commandment General Home Guards. An officer of the 1990 batch, Viswanathan was Commissioner of Police, Coimbatore City from 2012 to 2015. He had also served as Assistant Superintendent of Police, Dharmapuri and the Superintendent of Police, Madurai. He has also served as DIG of Intelligence. As the former Additional Commissioner of Police (Law and Order) in Chennai, the city is not new to him.

In the last 10 months alone, Chennai has seen three officers assume charge as Commissioner of Police in the city.
