Rihanna has obtained a restraining order against a man who was allegedly lurking outside her house last week.

The unidentified man was caught hanging around her Hollywood Hills home in California for three hours, by her bodyguards, who initially believed that he was scaling a fence, according to gossip website TMZ.com.

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 beauty and her mansion.

Meanwhile, another man was 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 home last month.

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

The stunning star 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 home.

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