The LAPD arrested Robert Melanson Monday night after he was spotted by private security officers at the singer's home near Sunset Boulevard. Rihanna was not at home at the time of the incident.
The 26-year-old was taken into custody without incident and was booked on suspicion of trespassing. His bail was set at $2,882.
Last February, a man was arrested after breaking into the star's home and sleeping in a bed at her house.
