McALESTER, Okla. (AP) _ Police raiding a home early Tuesday threw a ``flash bang'' device through a bedroom window, burning a sleeping couple when the device landed on the bed.

Narcotics Task Force Commander Richard Sexton said police used the device while serving a search warrant for drugs and guns at the home of Nina and Eugene Kirk in Krebs, about 10 miles east of McAlester.

``This was a distraction device, and it's not meant to hurt anyone,'' Sexton said. It landed on the bed accidentally, he said.

Nina Kirk was taken to Hillcrest Burn Center in Tulsa, where she was in stable condition with second-degree burns over 25 percent of her body.

Eugene Kirk was treated at McAlester Regional Health Center. Then, wearing ankle-to-thigh bandages on both legs, he went to court to request a mistrial on an unrelated firearms charge. The mistrial was granted.

Kirk is charged with illegally possessing a handgun found by the same group of police in his home in March 1995.
