Oregon ? A Portland massage therapist accused former Vice President Al Gore of “unwanted sexual contact” at a hotel during an October 2006 visit, but no charges were filed due to lack of evidence, law officials said Wednesday.

An attorney representing the woman contacted police in late 2006, said Multnomah County District Attorney Michael Schrunk. Schrunk said the woman — who has not been identified — refused to be interviewed by detectives and did not want the investigation to proceed.

The woman, however, contacted police in January 2009 and gave a statement, saying Gore tried to have sex with her during an appointment at the upscale downtown Hotel Lucia, where Gore was reportedly registered as “Mr. Stone.”

The National Enquirer first reported the allegations Wednesday, identifying the accuser as a 54-year-old woman.

Gore family spokeswoman Kalee Kreider said the former vice president has no comment. Gore and his wife announced June 1 they were separating.

A police report prepared in 2007 said the alleged incident occurred Oct. 24, 2006. Gore was in Portland to deliver a speech on climate change.
