A Kentucky appeals court upheld a $6.1 million award to a former fast food worker who was forced to strip in a McDonald's restaurant office after someone called posing as a police officer.

The appellate court on Friday ruled that Illinois-based McDonald's Corp., knew about a series of hoax calls to restaurants around the country, but didn't warn employees before Louise Ogborn was strip searched and sexually assaulted as the result of such a call in 2004.

The appeals court ruled that to reverse the verdict would cut against the weight of the evidence.

Ogborn was 18 at the time of the call to the store about 20 miles south of Louisville. A Kentucky man, Walter Nix Jr., the fiance of a McDonald's assistant manager, served a prison sentence for sexually abusing Ogborn during the call. A Florida man, David Stewart, was acquitted of making the hoax call. Police have said similar calls stopped after Stewart's arrest.

McDonald's spokeswoman Danya Proud said the company doesn't dispute what happened to Ogborn, but is disappointed with the decision of the appeals court.

"However, it has been our position throughout these proceedings that she was the victim of a malicious hoax perpetrated by individuals not representing McDonald's," Proud said.
