Chief Secretary Girija Vaidyanathan, Director General of Police, T K Rajendran, Chennai Police Commissioner, S George apprised Governor Rao.
The meeting assumes significance as AIADMK is awaiting a formal invite from Rao to form the government even as the camp led by O Panneerselvam is expecting an opportunity to "prove" their strength in the floor of the Assembly.
Allegations of AIADMK legislators being held in a resort here against their wishes, which has, however been denied by the AIADMK, and a related petition in the Madras High Court were among the topics that were discussed, sources said.
