Authorities say a man who posed as an undercover police officer kidnapped a woman in Seattle, drove her hundreds of miles to his home in Oregon, and kept her makeshift cell from which she eventually escaped and found help. The FBI said Tuesday that police in Reno, Nevada, arrested 29-year-old Negasi Zuberi after he fled from his home in Klamath Falls, Oregon, where he had taken the Seattle woman. It says he is charged with interstate kidnapping and that authorities are searching for additional possible victims after linking him to sexual assaults in at least four other states. It says Zuberi may have also lived in California, Washington, Oregon, Colorado, Utah, Florida, New York, New Jersey, Alabama, and Nevada.
