Singer Rihanna has obtained a restraining order against a man who was caught eyeing her Hollywood Hills property here last week.

The unidentified man was caught hanging around her house for three hours by her bodyguards, who initially believed he was scaling a fence, reports femalefirst.co.uk.

Police were called to the property but the man had already fled the scene before they had arrived.

However, they managed to track him down and arrested him on an unrelated vandalism charge.

He has now been ordered to stay at least 100 yards away from the 26-year-old and her mansion.

Although, police aren't convinced the man even knew the house he was eyeing up belonged to Rihanna.

Meanwhile, another man was a charged with stalking, menacing and harassment and held without bail after writing a string of insulting notes and delivering them to the star's rented New York house last month.

She was also forced to put her estate in Pacific Palisades, California, on the market in May after stalkers kept showing up unannounced.

She secured a three-year restraining order against Steveland Barrow in March 2013, after he broke into the property next door, which he wrongly believed to be her house.

Robert Melanson was also ordered to stay at least 100 yards away from the "Umbrella" hitmaker's house and, or, place of business, after the male trespasser was caught creeping around on her roof in June 2013.
