London, (Agencies): Facebook founder Mark Zuckerberg has said he feared for his safety after an obsessed Indian-origin fan stalked him on his own social networking site and tried to contact him.

According to a media report Pradeep Manukonda, 31, bombarded the internet billionaire with online messages.

Manukonda allegedly flooded Zuckerberg, 26, with emails and even sent him flowers and a hand-written note.

Zuckerberg filed legal papers claiming the stalker had tried to "follow, surveil and contact Zuckerberg using language threatening his personal safety", gossip website TMZ claimed.

Manukonda is said to have tried to visit Zuckerberg at Facebook offices in Palo Alto, California, to ask for money for his family.

According to the legal documents, Facebook security also caught Manudoka at Zuckerberg's modest four-bedroom home in Palo Alto Jan 24.

According to the report, police gave Manukonda a verbal warning but Zuckerberg claims he has continued to contact him through email and with a hand-written letter dated Jan 28.

The hand-written note reads: "Thank you for your valuable time and attention towards my problem adding "I owe my entire life at your service. Please help me, and then I am ready to die for you. Please understand my pain."

Manukonda has been asked to stay at least 300 yards away from Zuckerberg by a judge, pending a hearing later this month.
