According to the affidavit, issued by the Charleston Police Department and obtained by PEOPLE, “there is probable cause to believe that [Ravenel] did commit the crime set forth and that such probable cause is based on the following facts” that are listed.

The document states that Ravenel “did knowingly, willingly, and unlawfully violate SC Statue 16-3-600(D)(1), Assault and Battery in the Second Degree” on Jan. 25, 2015.

The affidavit states that “the victim, to be named later at the court’s discretion, was working for the defendant as a nanny at the above location. While inside the location, [Ravenel] undressed and made sexual advances on the victim.”

According to the affidavit, which describes graphic details of the alleged assault, Ravenel proceeded to sexually assault the nanny before she escaped.

“After escaping the assault, the victim called her then ex-husband and sister and told them of the incident, fled the scene and notified several family members of the incident. Photographs were then taken immediately of the injuries to her neck and chest,” the affidavit states. “Detectives corroborated the incident date and location through employment records of the victim and defendant, and interviewed multiple witnesses, to be named at the court’s discretion, who substantiated the post-assault information. Detectives also retrieved the photographs taken by the victim, which are appropriately time-stamped in reference to the incident.”

“The victim, having an extensive work history with the defendant, was shown a single-photo of the defendant, of whom she immediately identified her assailant,” the affidavit states.

Police began investigating Ravenel in May after a woman reported him for sexual assault. A former nanny to his children named Dawn, and known to fans of the Bravo show as “Nanny Dawn,” claimed to PEOPLE that she is that woman. Dawn, who asked that her last name not be used, was featured on the show caring for Ravenel’s two children with ex-girlfriend and costar Kathryn Dennis, daughter Kensie, 4, and son Saint, 2½.

The affadavit corroborates what Dawn told PEOPLE in May, when she claimed that in January 2015, she reported for work, and Ravenel headed to dinner with friends.

“Thomas returned home from an evening with friends,” she said. “I had just finished making baby food and was drying baby bottles.”

Dawn claimed Ravenel turned off the lights, and she called out that she was working in the kitchen and needed to see. At that point, she alleged Ravenel entered the kitchen and attempted to kiss her.

“I told him ‘this isn’t appropriate. I work for you.’ He then hugged me as an alternative,” she said. “I had baby bottles in my hands, so I couldn’t hug him. It felt like he was putting his weight on me.”

After suggesting Ravenel go upstairs, Dawn said the incident escalated.
