On Saturday, June 2, the "Come Back To Me" singer called police to check on the well-being of 1-year-old son Eissa Al Mana while the toddler was with Jackson's estranged husband, Wissam Al Mana, at the Nobu hotel in Malibu, California.
Randy told ET that his sister called 911 after being contacted by a nanny who was helping Al Mana care for the child at the time. The source also claims Al Mana has been verbally aggressive to Jackson in the past. The watch commander added that everything checked out okay and when the police left and the child remained at the hotel.
Janet, 52, welcomed her baby boy with then-husband Wissam Al Mana in January 2017.
Terrified by his actions, she locked herself in the bathroom to contact Jackson.
ET has reached out to her sibling, Randy Jackson in order to find out more about the police phone call.
Four months after Eissa's birth, Janet and Qatari business magnate Wissam split after five years of marriage however it was thought the exes remain amicable for the sake of their son.
"All Janet wants to do is move forward and be the best mother to her son and to be happy", the source said.
