The daughter of late soap star Kristoff St. John and professional boxer Mia St. John got arrested in Idaho after allegedly stripping down in a supermarket ... and cops say she later tried to escape from jail.
According to the arrest affidavit, obtained by TMZ, cops in Boise were called to a WinCo around 8 PM Monday night for a report of indecent exposure, with a store employee telling police Paris St. John was naked in the store, praying and meditating.
When cops arrived, they say Kristoff's daughter was naked in the store's front office. The woman who called police ultimately convinced Paris to put her clothes back on.
Police say Paris was arrested for indecent exposure and transported to Ada County Jail ... where cops claim she stood up and ran out of the jail's sally port when the door opened for an entering officer.
Cops say they told Paris to stop, but she ignored them and continued fleeing ... with police running after her, grabbing her and bringing her to the ground.
Paris was booked on three misdemeanor charges ... indecent exposure, escape, and resisting or obstructing officers. We're told Paris is currently getting mental health treatment.
The St. John family has been through a ton of trauma ... Paris' dad died 3 years ago from heart disease triggered by alcohol abuse ... and in November 2014, her brother Julian died by suicide.
Paris' mom, former professional boxer Mia St. John, has been open about the family's mental health struggles ... Mia says Kristoff suffered from bipolar disorder and alcoholism, while Julian suffered from schizophrenia.
