It was alleged that the key personnel occupying posts of prominence in the State were intentionally targeting the judiciary by making derogatory posts on social media platforms against judges.
The Andhra Pradesh High Court on Tuesday made it clear that freedom of speech does not mean anything can be said or posted on social media.
CBI counsel Chennakesavulu informed the bench of Justice Joymalya Bagchi and Justice K Suresh Reddy that the investigating agency needs more time to conduct an in-depth probe.
UP Police ADG said police in districts across the state regularly monitor online activities through their social media cell and ensure action over objectionable content.
The accused had posted the alleged defamatory matter on the Facebook page of the minister, he said.
In connection with the case, the officials carried out a search operation at Kazimar Street, K Pudur, Bethaniyapuram and Mehaboopalayam in Madurai.
