This comes after Dana Holmes claimed she was illegally strip searched after a DUI arrest in May. She's has already filed a lawsuit.
The LaSalle County Sheriff denies that Holmes was strip searched.
The department says deputies believed she tried to kick them while in custody.
Terry Ekl, who is an attorney for the plaintiffs, says all of them were stripped naked and forced to use a hole in their padded cell floor as their toilet.
"Tremendous human indignities occurred to all four of these people. Regardless of what the LaSalle County authorities are trying to peddle, they were stripping people who they felt needed discipline or were not being compliant with their instructions," said Terry Ekl, attorney.
ABC7 Eyewitness News was unable to reach the LaSalle's Sheriff's Department for a comment.
