Police are investigating a family disturbance and possible assault at the home of Michael Jackson's mother.
Los Angeles Sheriff spokesman Steve Whitmore said no-one was arrested after deputies were called to Katherine Jackson's home around 1.10pm local time yesterday.
He said deputies concluded there had been a physical altercation between two people and the case remains under investigation, as a possible battery.
The incident is the latest drama for the Jackson family.
A relative reported Katherine Jackson missing on Saturday, but authorities located her with other family members in Arizona.
Authorities believe Katherine Jackson, the mother of Michael Jackson and the guardian of the pop legend's three children, is safe in Arizona with family members after she was reported missing.
The disclosure came after another concerned family member officially reported her missing amid a dispute over the estate of her superstar son.
Katherine Jackson is reportedly with her daughter Rebbie in Arizona and following a doctor's orders to rest.
