The alleged stalker of Facebook CEO Mark Zuckerberg has been reportedly trying to turn the tables by filing a defamation lawsuit, claiming that the social media mogul is trying to destroy his reputation.

According to reports, Indian national Pradeep Manukonda has filed a lawsuit in an Indian court against Mark Zuckerberg and a local politician, accusing them as the ones behind a slew of attacks against him.

The alleged stalker claimed he was “stabbed from the back side” and that Mark Zuckerberg is responsible for making a fake Facebook page, saying he is a member of Al-Qaeda. Pradeep Manukonda has reportedly convinced a judge already to issue a court order, preventing 28-year-old Zuckerberg from doing anything that could damage Manukonda’s reputation.

Previous reports have stated that Mark Zuckerberg obtained a restraining order in February last year against 31-year-old Pradeep Manukonda, after the Indian national allegedly blasted him with several threatening online messages, sent him flowers and even showed up at his home. The internet billionaire claimed he was fearful of his safety. The restraining order banned the alleged stalker from going within 300 yards of Zuckerberg, his sister Randi Zuckerberg, and his then-girlfriend Priscilla Chan — whom he recently got married to.

The Facebook CEO filed the legal docs, claiming Pradeep Manukonda had tried to “follow, surveil and contact Mr Zuckerberg using language threatening his personal safety.”

The Indian national has been reported to have tried to visit Zuckerberg at Facebook offices in Palo Alto, California to ask money for his family.

The legal documents filed by Mark Zuckerberg stated that Facebook security also caught Pradeep Manukonda at Mark’s modest, four-bedroom home in Palo Alto on January 24 last year. Security are understood to have caught the alleged stalker just as he was about to walk up the front steps.

The authorities gave Manukonda a verbal warning at first, but Mark Zuckerberg claimed the alleged stalker continued to contact him through email and with a handwritten letter on January 28.

The handwritten note read, “Thank you for your valuable time and attention towards my problem.”

“I am indeed very grateful to you. If I get a chance to work with you in the near future it would be my honour. I know I am working with a man of values. Thank you for being a source of inspiration to all of us,” the letter went on.

In one of his Facebook messages to Mark Zuckerberg, Manukonda wrote, “I owe my entire life at your service. Please help me, then I am ready to die for you. Please understand my pain.”

Meanwhile, in a message to Mark’s sister, Randi Zuckerberg, the alleged stalker wrote, “I really need your help…my dear sister.”

A hearing on Manukonda’s lawsuit against Mark Zuckerberg is scheduled for next week in India.

Facebook CEO Mark Zuckerberg is currently facing a class-action lawsuit from the shareholders of the said social networking site, claiming that Zuckerberg had inside information that the stock of the company was grossly overvalued and that he got rid of Facebook stocks even before their post-IPO flop.

According to reports, the class-action lawsuit against 28-year-old Mark Zuckerberg claims that the Internet entrepreneur hid the truth there was some kind of fault in the Facebook business model, that there was not enough advertising revenue to support a stock valued at the price of $38 a share.

The class-action lawsuit also claims that Morgan Stanley, J.P Morgan Chase, and Goldman Sachs all gave Mark Zuckerberg a warning before the IPO that Facebook was seriously overvalued, but that information was “selectively disclosed” to the company’s biggest investors.

The shares of Facebook Inc. went down 82 cents to close at $US26.90, after trading shortly as low as $US26.44. Additionally, the shares have fallen about 30 per cent since the debut of Facebook on May 18.
