A 50-year-old man who said he felt that airport screeners were "harassing" him stripped naked at Portland International Airport, police in Oregon said.

Police charged John E. Brennan with disorderly conduct and indecent exposure after he disrobed while going through the security screening area at the airport Tuesday evening.

"When interviewed about his actions Mr. Brennan stated he fly's a lot and had disrobed as a form of protest against TSA Screeners who he felt were harassing him," a police incident report said.

He was not intoxicated or under the influence of drugs at the time, police said.

Brennan was scheduled to fly on Alaska Airlines from Portland to San Jose, California.

Police said screeners asked him "numerous times" to put on his clothes, but he refused.

"Mr. Brennan's actions caused two screening lanes to be closed and while some passengers covered their eyes and their children's eyes and moved away from the screening area, others stepped out of the screening lanes to look, laugh and take photos of Mr. Brennan," the police report said.
