(CNN) -- Jewish organizations called for a Romanian official to resign and face a criminal investigation after he wore a Nazi uniform during a fashion show over the weekend. 

Radu Mazare, the mayor of the town of Constanta, wore a Nazi uniform during a fashion show over the weekend. 

Radu Mazare, the mayor of the town of Constanta, and his 15-year-old son "entered the stage marching the clearly identifiable Nazi 'goose step,'" the Center for Monitoring and Combating anti-Semitism in Romania said in a letter to the country's prosecutor general. 

The organization's director, Marco Katz, said Mazare had broken Romanian law and encouraged his son to do the same, "educating him to treat the law with contempt." 

Katz said Mazare was sending a message "that to wear Nazi uniforms and to march the Nazi steps is legal and 'in vogue' in Romania." 

He urged the authorities and the head of Mazare's Social Democrat party to show that message "will be strongly countermanded." 

Mazare, 41, said he had not noticed the Nazi swastika symbol on the uniform before he wore it, according to the Romanian Times newspaper. 

"I checked it before I put it on but the swastika was very small and I didn't see it," he said. "I really liked the look of the uniform after seeing it in the Tom Cruise film 'Valkyrie.' I bought it from a costume hire shop in Germany." 

A top Nazi hunter said Mazare should quit. 

"The proper thing for you to do is to admit your mistake, apologize for it and resign your position," Efraim Zuroff of the Simon Wiesenthal Center in Jerusalem wrote to Mazare. Zuroff sent CNN a copy of the letter.  QUESTIONS:
