Any general aviation fuel dealer who fails or refuses to pay over to the state the tax on general aviation fuel at the time required in this chapter or who fraudulently withholds or appropriates or otherwise uses such moneys or any portion thereof belonging to the state is guilty of theft and shall be punished as provided by law for the crime of theft, irrespective of whether such general aviation fuel dealer has or claims to have any interest in such moneys so received.
