An adviser to the Polish president has accused U.S. authorities of "absolute ignorance" in seeking the arrest of film director Roman Polanski, a Holocaust survivor, while he was in Poland last week for the opening of a Jewish history museum.

U.S. authorities sought Polanski's arrest on 1977 charges of having sex with a minor.

Polanski attended the opening of the museum in Warsaw on Oct. 28 before traveling to Krakow, his childhood city. Polish authorities questioned him there because of the U.S. request, but refused to arrest him.

Tomasz Nalecz, adviser to President Bronislaw Komorowski, called it inappropriate to seek the arrest of a "child of the Holocaust" at the opening of the museum, which highlights Poland's role as a safe haven for Jews for centuries before the Holocaust.
