TMZ reports the actress allegedly had an argument with her then-girlfriend, photographer Tasya van Ree, in the Seattle-Tacoma International Airport on Sept. 14, 2009. The altercation reportedly resulted in Amber being arrested for misdemeanor domestic violence.
According to the gossip site, "Amber allegedly grabbed and struck Tasya in the arm, which upset Tasya and triggered the arrest."
In an audio recording from Amber's court appearance on Sept. 15, 2009, a prosecutor can be heard saying "the state is declining to file charges." Another voice cites "cross-state implications," which TMZ reports boiled down to the fact that Amber and Tasya both lived in California while the incident allegedly took place in Washington.
Reports have suggested Amber dated Tasya from 2008 until early 2012, although the timing was never publicly confirmed.
After filing for divorce from Johnny on May 23, Amber obtained a restraining order against him, which a judge granted on May 27.
In court, Amber appeared to have a bruised eye, which she said was the result of her husband throwing an iPhone at her face during an argument on May 21.
She has so far declined to file a police report over the incident; last week, a source said she was avoiding that formal step because she "doesn't want to bury him" with an arrest and trial.
While some eyewitnesses have claimed they never saw evidence of Amber's injuries following Johnny's alleged abuse, others, like iO Tillet Wright, who is named in Amber's court papers as a witness, have dismissed those denials as "victim blaming."
"I've had enough. I saw the bruises. Many times. And the fat lip. And the cut head," the photographer, writer and MTV host tweeted after reading a TMZ report in which doormen claimed Amber suffered no visible injuries.
"How much evidence does a woman need to present?! She has photos, texts, witnesses, and filed a restraining order," iO continued.
"This culture of victim blaming makes me sick. I'm a witness. I'm here. I'm standing up. I can't take any more of this witch hunt. I was on the f------ phone when he hit her. I HEARD HER SCREAM. I will testify. Here and in court. Under oath. WHAT ELSE DOES A WOMAN NEED?"
Johnny's lawyer, Laura Wasser, meanwhile, has accused Amber of "attempting to secure a premature financial resolution by alleging abuse."
