A trespasser has been arrested at Rihanna's house.

A man was caught red-handed by the singer's security team as he attempted to scale the wall surrounding her plush Pacific Palisades mansion at 11am on Friday morning (04.10.13).

The would-be home invader fled the scene, but police caught up with him a mile away from the superstar's $12 million property, TMZ reports.

This comes after a group of burglars tried to break into Rihanna's home last weekend - only to be thwarted by the burglar alarm, which was set off when they threw a chair through a sliding glass door.

It appears the trespasser could be one of the original gang as he looked ''very much'' like one of the suspects when police reviewed the security footage from the first break-in.

The 25-year-old star wasn't at home during either of the incidents since she is currently on the Australian leg of her 'Diamonds' world tour.

Cops are still on the lookout for the original intruders, who entered the grounds by cruising up Rihanna' private road by car, ignoring the sign reading, 'Smile, you're on camera', in her driveway.

This marks the third incident in recent months of attempted break-ins at Rihanna's place. In June, a man was caught by her security team climbing onto her roof, while back in February a wannabe thief accidentally broke into her neighbour's house instead of hers.
