Krishnan was chairman of the Panchayat Union in Manamadurai from 1970 to 1976 and president of Theethanpettai village panchayat from 1970 to 1976.

Krishnan was elected to the Fourth Lok Sabha in 1967-1971 and to the Fifth Lok Sabha in 1971-1977, on voth occasions from the Sivanganga parliamentary constituency. Thereafter, in 1996, he was elected from Sivaganga state assembly constituency to the Tamil Nadu Legislative Assembly as a Dravida Munnetra Kazhagam (DMK) candidate.

Krishnan was Minister of State Highways and Ports in the Government of Tamil Nadu from 1998 to 2001.

Krishnan was murdered on 20 May 2003. He was hacked to death near his K. K. Nagar residence on 20 May 2003. Several arrests were made and when the DMK came to power in Tamil Nadu in 2006, the case was transferred to Chittoor in Andhra Pradesh after the All India Anna Dravida Munnetra Kazhagam (AIADMK) sought intervention by the Supreme Court of India. The AIADMK said that a fair trial might not be possible in a Tamil Nadu court because the primary accused, M. K. Alagiri, was the son of Karunanidhi, by then the DMK Chief Minister. Alagiri and his co-accused were found not guilty in 2008 due to lack of evidence.
