A former judge convicted of exposing himself while presiding over jury trials by using a sexual device under his robes was denied parole on Tuesday.

The Oklahoma Pardon and Parole Board voted 5-0 against granting early release to former Judge Donald Thompson, who was sentenced to four consecutive one-year jail terms in August for indecent exposure. Prosecutors claimed Thompson used a device called a penis pump while presiding over trials between 2002 and 2003.
