Mark Zuckerberg, the multi-billionaire CEO of Facebook, has obtained a restraining order against a man who has sent him messages through Facebook, left flowers and a handwritten note at his home and showed up in person at Facebook officers looking for him.

According to TMZ, the stalker is 31-year-old Pradeep Manukonda , who at one point,was intercepted by security while walking up to Zuckerberg’s home.

TMZ reports that Manukonda repeatedly discussed some problem that he wanted Zuckerberg to help him with.

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

A judge has ordered Manukonda to stay at least 300 yards away from Zuckerberg, his sister and his girlfriend.

Manukonda subsequently apologized for his behavior.

“I’m a peaceful guy … I’m sorry he thought I was trying to harm him,” he told TMZ.
