Kolkata: Even as the controversy surrounding the arrest of Jadavpur University professor Ambikesh Mahapatra over a cartoon on Chief Minister Mamata Banerjee is still afresh, the West Bengal Police has also started probing a complaint of defamation against social networking sites, including Facebook.
The complainant alleges malicious campaigning against Mamata Banerjee on social networking sites.
The case was handed over to the CID on Wednesday.
The police is now tracking IP addresses from where the posts were made.
Reacting to the recent controversies surrounding the Mamata Banerjee government, Trinamool Congress MP Kabir SUmna said, "This is a complete turnaround from what Mamata would have done had she been in the Opposition. The West Bengal government seems to be suffering from paranoia."
