A woman was arrested Sunday afternoon after firing multiple bullets from her vehicle toward RihannaThe house… TMZ has found out.

Law enforcement sources tell us the suspect, described as a woman in her 30s, drove near the Los Angeles property and fired several shots in the direction of the home. It is unclear what sparked the incident.

Our law enforcement sources tell us the singer was home at the time of the shooting but is fine. It is not clear if A$AP Rocky and his children… RZA, riot pink and Rocky – were in the house at the time.

Police quickly responded to the scene and detained the woman without further incident. Authorities are now investigating the motive.

We reached out to Rihanna’s representatives…so far, we have not heard back.
