Kimberly Mathers, ex-wife of rapper Eminem, was arrested following a reported accident on a metro-Detroit waterway Sunday (July 8).

According to the Macomb County Sheriff Department, Mathers, 26, was arrested on an outstanding bench warrant issued because she failed to comply with a court order stemming from a previous charge of disturbing the peace in Warren, Mich. Sheriff deputies were called to the area to investigate a reported accident on the water involving a jet ski watercraft when they found Mathers and another woman walking nearby carrying life jackets. After officers made contact with the pair, and determined they had in fact been operating the jet ski, a routine identity check was performed.

Mathers was then arrested and transported to the Macomb County Jail. After the arrest, a deputy reportedly found a baggy containing a white, powdery substance in the rear of the patrol car used to transport Mathers. Other charges could result after the completion of lab tests and a further investigation, according to a press release issued by the Macomb County Sheriff Department.

Mathers was released on $3,000 bond and is scheduled to be arraigned July 11 in Warren’s 37th District Court before Judge John Chmura. Her friend was released at the scene.
