Janet Jackson called Police to check on son, Eissa's welfare while he was with his dad

Janet Jackson called the police on Saturday to check on the welfare of her son Eissa Al Mana while he was in the care of his father, Wissam Al Mana.

TMZ reports:

Law enforcement sources tell us Janet made the call to Malibu authorities late Saturday night, asking cops to check in on her son … who was with her estranged husband, Wissam Al Mana, at the Nobu Hotel. We’re told police did, in fact, check in — but found no one to be in danger. Sources say cops told the 2 parties — Janet and Wissam, in this case — to handle the matter civilly. 
It’s unclear if Janet was on the scene or not, though. 

According to a report … Janet was supposedly tipped off to some alleged aggressive behavior displayed by Wissam, which concerned a nanny enough to alert Janet. 

Janet’s brother, Randy, revealed that Wissam’s abuse was a major factor in Janet’s decision to leave their marriage.
