Attempted burglary on Rihanna's USD 12m LA pad gets thwarted by security alarm

Law enforcement sources told TMZ.com that the intruders drove up the private road leading to the singer's house, walked to the backyard and threw a chair through a sliding glass door.

However, they were scared off apparently by the alarm, as they left without entering into the house.u00a0
