This is not OK.
Cops believed the same guy who threw a patio chair through the singer's sliding glass door and ran, also tried to scale a wall around her house at 11 a.m. today!
The Barbados beauty's security called 911 and cops came out to arrest the trespasser—who they found about a mile from her home!
Law enforcement sources say they've reviewed the security tapes from the attempted burglary over the weekend, and the alleged tresspassor IS the same guy!
The unidentified 27-year-old has been apparently booked on burglary charges!
Don't mess with Bad Gal RiRi's stuff, because she'll gettcha!
