A Knox County mayoral candidate was arrested in Los Angeles on Wednesday, according to the Los Angeles County Sheriff's Department.

Rhonda Gallman, 50, is being held at the Century Regional Detention Facility in Lynwood, California. She was charged with four counts of preventing or dissuading a victim or witness from testifying in court, according to the sheriff's department. Officials said her bond was raised from $100,000 to $400,000 on Sunday.

Gallman is running as a Democrat in the Knox County mayoral race.

She is accused of trying to convince witnesses not to testify in a criminal case against her son, according to the Los Angeles County District Attorney's Office.

Gallman's son Jamahl Thomas, 24, faces two counts of attempted murder and one count each of conspiracy to commit murder and shooting at an occupied motor vehicle, according to the DA's office.

In January, a GoFundMe page was set up for Gallman. The page said she needed help traveling to California because her son was arrested, and she wanted to be there for him.

Linda Haney is the only other candidate in the Democratic primary for Knox County Mayor. Bob Thomas, Glenn Jacobs and Brad Anders are all running in the Republican primary. The primary will be held May 1.
