Renate Langer, a 61-year-old former German actress, has reported to the Swiss police that the film director Roman Polanski raped her at a house in Gstaad in February 1972, when she was 15. Ms. Langer is the fourth woman to publicly accuse Mr. Polanski of sexual assaulting her when she was a teenager. The police in St. Gallen, Switzerland, confirmed that they met with Ms. Langer on Sept. 26. Ms. Langer provided The New York Times with a copy of an email - sent by a Swiss police officer - saying that another office would make the determination as to whether she could pursue a criminal complaint. Switzerland has eliminated its statute of limitations on child sex abuse cases. Ms. Langer said ... she had approached the Swiss police because she believed the statute of limitations would allow her complaint to be investigated. Harland Braun, a lawyer for Mr. Polanski, the 84-year-old award-winning French-Polish film director, declined to comment. Mr. Polanski pleaded guilty in 1977 to unlawful sex with Samantha Geimer when she was 13. In August, a woman in Los Angeles, identified only as Robin M., came forward at a news conference to report that Mr. Polanski had sexually assaulted her in 1973 when she was 16. In 2010, the British actress Charlotte Lewis also accused Mr. Polanski of abusing her sexually when she was 16. Mr. Polanski has been living in exile from the United States since fleeing the country in 1978 on the eve of his sentencing in the Geimer case.
