He welcomed the setting up of a special team to investigate the murder of party's state leader V. Ramesh.
Speaking to reporters here, Naidu alleged some fundamentalist forces may be behind the attacks on BJP and Hindu Munnani leaders in Tamil Nadu and "there seems to be a pattern in these attacks".
According to him the recurrent killings of BJP and other Hindu outfit leaders in the state showed that these were not isolated incidents.
Naidu said Tamil Nadu Police should take it as a challenge to solve the political murders.
Ramesh, 52, a chartered accountant, was hacked to death by four men Friday night at Salem, around 340 km from Chennai.
The BJP leader also took the central government to task on several issues and added that the United Progressive Alliance was misusing the Central Bureau of Investigation (CBI).
He alleged that the virtual clean chit given to Mulayam Singh Yadav by the CBI in an illegal assets case was in exchange for the Samajwadi Party's support to the food security bill to be introduced in the ensuing parliament session.
