If a criminal action or proceeding under ss. 946.80 to 946.88 is brought, or intervened in, to punish, prevent or restrain any such violation, the running of the period of limitations with respect to any civil action or proceeding, including an action or proceeding under s. 946.87, which is based in whole or in part upon any matter complained of in the criminal action or proceeding shall be suspended for 2 years following the termination of the criminal action or proceeding.
