Singer Janet Jackson called the police to check on the welfare of her one-year-old son Eissa Al Mana while the child was with his father, Wissam Al Mana.
Spokesperson for the Malibu Lost Hill's Sheriff's station told People magazine that the baby was with Jackson' estranged husband at the Nobu hotel in Malibu, California, when she called the authorities round 10 pm on Saturday.
"Deputies were there (and) called to the scene. They decided the child was okay and they left," the spokesperson said.
The 52-year-old singer was not at the hotel at the time.
The pop star's brother Randy Jackson told Entertainment Tonight that she was concerned after their nanny grew "terrified" by Al Mana's behaviour and "locked herself in a bathroom, so she could contact Janet."
