Actress Ashley Judd has become embroiled in a legal feud with her sister Wynonna over allegations the country singer placed a tracking device on her car as part of an ongoing custody battle.
The Double Jeopardy star filed a police report in Tennessee last month, after a mechanic found a wireless GPS tracking device on her vehicle.
In legal documents, obtained by editors at ABC News, Ashley reportedly told cops she believed Wynonna was responsible for the GPS, and an investigation launched by authorities traced the device back to a private investigator, who claimed to be "working for" the musician.
The papers reveal the sisters are currently embroiled in a custody dispute over Wynonna Judd's teenage daughter, who Ashley is said to have custody of, and the actress claims the device was "placed there in order to track their movement".
Wynonna has admitted to having the tracker fitted, but insists she was only trying to keep tabs on her daughter, from her relationship with ex-husband Arch Kelley, as the youngster also drives the vehicle, according to NashvilleGab.com.
Kelley has denied any involvement in the scandal and authorities appear to have put the case on hold, as it is currently listed as inactive.
The Judds have refused to comment on the ABC News report.
