Southern California Black Lives Matter activist Jasmine Richards was sentenced to 90 days in jail Tuesday just days after being convicted of interfering with an arrest under a law that once described her action as “lynching.”

The social justice organization tweeted the results of the sentencing in Los Angeles Superior Court, adding that Richards sentence includes 18 days time served. The Los Angeles Times reported that she also got three years probation.

Richards was arrested by Pasadena, Calif, police officers last year when a woman who had allegedly left a restaurant without paying joined her and a group who had gathered in a nearby park. Prosecutors say Richards tried to start a riot when police tried to arrest the woman. Richards was taken into custody by police several days later.

Richards was convicted under a 1933 California Penal Code that had once read: “The taking by means of a riot of any person from the lawful custody of any peace officer is a lynching.”

The language of the code was changed when Gov. Jerry Brown signed a bill last year that removed the word “lynching” from the law and defines a person found guilty of the action as a felon.

Richards had faced up to four years behind bars.
