[1] Dr. K. Radhakrishnan did his PhD from the Department of Criminology from the University of Madras for seminal research on 'Tactical and Strategic Police Response to Communal Violence: Coimbatore, a case study', in October 2009.

In a dramatic midnight encounter with the LTTE on 18 February 1990, he led the mission that saved lives of Eelam People's Revolutionary Liberation Front (EPRLF) militants and their leader K. Pathmanabha, who were lodged in the Mandapam Refugee Camp.

During this period he was proven instrumental in the leading to the arrests of two of the assassins of the former Prime Minister Rajiv Gandhi and LTTE terrorists who escaped from prison in Chennai.

[6] In July 1997, Radhakrishnan was promoted to the function of the Deputy Inspector-General of Police in the Trichy Range, which comprised four districts, during which he successfully held against the Tamil Nadu Liberation Army, leading to the arrests of 50 TNLA members and its leader.

In 2002, he was promoted to Inspector-General of Police in Vigilance & Anti-Corruption, Chennai and in 2006 moved to the department of Law & Order North Zone, Tamil Nadu.

[10] Coimbatore City, popularly known as the "Manchester of South India" due to its booming textile industry, witnessed several debilitating communal riots from 1980, culminating in the serial blasts of 1998 that claimed more 50 lives and injured hundreds.

In an apparent retaliation, the Muslim fundamentalist organisation Al Ummah, within 2½ month engineered serial blasts on 14 February 1998 in the run-up to the Parliamentary Elections killing 63 (53 Hindus), maiming 245 and destroying properties worth several crores of rupees.

Organising extensive searches that led to the seizure of 684 lethal weapons, 584 bombs, 20 firearms, one lakh detonators, cash, addresses of the benefactors of the accused, fundamentalist literature, incriminating documents and photographs, he and his team made sure that by video-graphing all the raids, there was no violation of code of conduct or human rights.

The action plan aimed at involving the community in policing spheres, in resolving the Hindu-Muslim discord and in bringing about a life free of communal violence for the residents of Coimbatore.

Besides the student community, CVC volunteers were involved in frisking passengers, checking baggage at important junctions, railway stations and bus stands during turbulent times.

However, with the introduction of All Women Police Stations (AWPSs) from 1993, their numbers escalated and correspondingly, the significance of their roles increased too with their duties covering resolution of family disputes and handling of dowry and other domestic-abuse issues.

Upon receiving an excellent reception to the workshops, the Government of Tamil Nadu extended the program to cover the existing police force in its entirety which numbered to a lakh.

[22] The program proved to be a useful platform through which the various inadequacies of the women police personnel in handling family disputes and other domestic conflicts were thrown into light.

K. Radhakrishnan's project, competing under the head "The use of new technologies to overcome barriers to deliver training and lifelong learning" amongst entries by officers belonging to 53 member nations of the Commonwealth, was the recipient of the prestigious award in 2002.

Select officers were trained in familiarization workshops that were held in Chennai and were presided over by K. Radhakrishnan and the Queen's Award project director Dr. Mangai Natarajan.

Study materials and user-guides were posted on the project website, with access to chat-room and forum facilities for exchange of guidance and support between officials in handling dispute and abuse cases.

Computers with keyboards were set up at each station in Tamil Nadu, along with adequate telephone lines and internet connections, making this a pioneering project in online-police training in India.
