Nina Thomas was arrested on April 13 in Austin, Texas, and charged with first-degree felony burglary of a residence with intent to commit aggravated assault with a deadly weapon, according to a court document obtained Thursday by ESPN's Jamison Hensley.
A team spokesman said the Ravens are aware of the situation but that Thomas did not notify the team of the incident.
Earl Thomas was not arrested, and an attorney representing Nina Thomas said Thursday that she "was wrongfully arrested."
According to an arrest warrant from the Travis County magistrate court, Nina Thomas told police that she confronted her husband at a rental home because she believed he was cheating on her.
Nina Thomas told police she used Snapchat to track Earl to the rental home, brought two other women with her, and found her husband and his brother in separate bedrooms with two other women.
According to the document, an officer viewed cellphone video footage that shows Nina Thomas placing Earl's 9 mm Beretta less than a foot away from her husband's head, with the safety disengaged and her finger on the trigger.
Nina Thomas told police she had called the other women to help confront her husband and took his handgun with an intent to "scare him," according to the document. She had taken the magazine out of the gun but was unaware of a round in the chamber.
According to the arrest warrant, Tiffany Loving, who was one of the women at the rental residence with the Thomas brothers, told police that Earl asked Nina to give him the gun, but Nina began hitting him with her free hand, striking him in the eye, arm and groin. Earl and Nina then fell on the ground and "tussled" for the gun, the warrant said.
The two women who arrived with Nina -- Camisha Garlow and Kayla Baham-Heisser -- were also arrested for burglary of a residence.
Earl Thomas, a seven-time Pro Bowler who turned 31 on Thursday, wrestled the gun away from Nina Thomas, according to the document. When police arrived at 3:41 a.m., they found Nina Thomas with a knife and chasing Earl, who had the gun.
Earl Thomas indicated in an Instagram post Wednesday night, which has since been deleted, that TMZ would be releasing details of the altercation and said he wanted to "get ahead" of the report.
"It's not really anybody's business," he said in the since-deleted post. "It pisses me off that it got out, but it's the world we live in today. But instead of talking about us, just keep us in y'all's prayers. Stuff like this happens."
Thomas said he is talking with his wife and is seeing their three children. Nina Thomas' first court appearance is scheduled for June 8.
Thomas is entering the second year of a four-year, $55 million contract with the Ravens and is scheduled to make $10 million this season. In his first year with the Ravens, Thomas reached the Pro Bowl after making 49 tackles and intercepting two passes.
"We became aware of the situation when we read and saw it on the reports late last night and early this morning," a Ravens spokesman told ESPN.
