The former Congress MP from Moradabad approached Hyderabad Commissioner of Police M Mahendar Reddy last week, seeking action against those responsible for posting and circulating the "defamatory" messages against him.
Deputy Commissioner of Police (Task Force) B Limba Reddy, however, said today that no case had been filed in connection with the matter, as the messages (on the app) did not attract the provisions of the Information Technology Act.
"He (Azhar) can file a defamation case if he wants to," he added.
Azharuddin, who played 99 Tests and 334 ODIs, captained India in three world cups.
