MUMBAI: Prosecutors in the Roman Polanski case are angry on the lawyers of Roman Polanski and deny that they tried to conceal evidence in his 32-year-old sex case. On the other hand, they have renewed their demands that an appeals court order Polanski to return to the United States for sentencing.

In a 26-page brief filed on Tuesday, two prosecutors who handle appellate matters for the district attorney‘s office argued that allowing Polanski to avoid extradition from Switzerland hurts the integrity of the judicial system more than revelations of alleged misconduct by a now deceased judge.

They also claim there has been a misinterpretation of an extradition treaty with Switzerland and that Polanski should be returned for a Court hearing in Los Angeles.

The 76-year-old film director fled the US in 1978 after pleading guilty to unlawful sexual intercourse with a minor.

He remains under house arrest in Switzerland.
