Soul singer Isaac Hayes has parted ways with the Comedy Central series South Park, citing the series' inappropriate ridicule of religious communities.

Hayes, who has voiced the character 'Chef' since the series began in 1997, released a statement through his spokesman Monday requesting a release from his contract because he "is disappointed with what he perceives as a growing insensitivity toward personal spiritual beliefs."

The Hollywood Reporter reports in a rejoinder issued later in the day by Comedy Central, Park co-creator Matt Stone described Hayes as a disgruntled Scientologist unhappy with a recent episode lampooning the organization's religious beliefs.
