This is seriously scary. A man was arrested attempting (and failing) to break into Rihanna's home in Los Angeles last night (Feb. 21).

According to TMZ, police said the intruder was given directions to RiRi's house, but entered the house next door to the pop stars by accident. The intruder was snooping around the property of a neighbor when he caught the attention of some other residents. The man was confronted by some of the neighbors who then detained him and called police when they fully accessed the situation. Wow, is that how citizens arrests go down? We're glad the watchful eyes of Good Samaritans helped to stop this guy before he could steal any property or even harm someone. You know what they say, if you see something, say something!

Rihanna recently purchased this property for $12 million in December. The mansion is 11,000 square feet and boasts seven bedrooms and nine bathrooms (that's a bathroom every 1200 square feet).

Okay, RiRi, we hope you had video cameras, but if you didn't before, you will now!
