VANCOUVER - A 30-year-old man from Vancouver Island charged with six counts of sexual assault is expected to appear in a U.S. court today.

Denver's District Attorney says in a news release that Colby Messer was charged after a 27-year-old woman alleged she was sexually assaulted at a hotel last November.

District Attorney spokeswoman Lynn Kimbrough says Messer was released after posting a $300,000 U.S. cash bond.

She says the conditions of his release include that he must surrender his passport, remain in Denver and wear a GPS tracking device.

Denver-based lawyer Ken Eichner, who is listed in court documents as representing Messer, declined to comment on the case.

Denver police identified four suspects by looking at hotel records and surveillance footage.

The affidavit says officers contacted police in Vancouver who told them that none of the men had a criminal record.

The document says Vancouver police told their Denver counterparts that driver licence records for the four men showed two of the men lived in Victoria and two lived in Port Alberni, B.C.
