NYPD sources tell TMZ that the model was arrested at her home and taken to the Midtown North Precinct -- as of 12:20 PM EST, Thursday, Campbell was still there.
We're told the incident occurred at 8:00 AM EST. The alleged victim, a 41-year-old woman, was struck in the head with an object, allegedly thrown by Campbell. The woman had a laceration on the back of her head. She went to Lenox Hill Hospital for stitches.
In 2000, Campbell pled guilty to hitting former personal assistant Georgina Galanis with a telephone. She was ordered to take anger management classes.
In 2001, another former personal assistant, Simone Craig, claimed Campbell threw a mobile phone at her. Campbell denied it and no charges were filed.
Campbell's rep issued this statement: "We believe this is a case of retaliation, because Naomi had fired her housekeeper earlier this morning. We are confident the courts will see it the same way."
A police source tells TMZ that Campbell will be charged with assault.
