Police say a man naked to his underwear at a Virginia airport checkpoint in a protest next to security procedures.

Airport police said the man took off his shirt and pants at Richmond International Airport on Thursday. He had scrawled across his chest a reference to the Constitution's 4th Amendment protections next to unreasonable search and seizure.

Police recognized the man as 21-year-old Aaron B. Tobey of Charlottesville, Va. He told police he was a student at the University of Cincinnati.

Tobey was interview by airport police and federal authorities, issued a citation for disorderly behavior and released. He is scheduled for arraignment on Jan. 10.

Russian President Dmitry Medvedev has asked prosecutors to review operations at Moscow's airports after flight delays left thousands stranded.

Freezing weather and power outages have disrupted more than 200 flights over the last three days at Moscow's Domodedovo and Sheremetyevo airports, causing frustrated passengers to stage protests in some airport terminals.

Rainfall from unusually warm weather created a dangerous sheet of ice that stalled air traffic at both airports.

Passenger Pavel Selin, a correspondent for Russia's NTV stranded at Sheremetyevo airport, today described conditions to RFE/RL's Russian Service.

"What is happening here can be called a total collapse and chaos," Selin said.

"People here not only are stuck for a couple of days, but they cannot get any information at all about their flights. There is not a single official representative of the airport or of Aeroflot. Everyone is gone."

Earlier, Moscow Transportation Prosecutor Yevgeny Pospelov was quoted by Interfax as saying that the authorities had launched a probe meant to, as he said, "protect the rights of passengers" amid complaints of irregular water supply in airport bathrooms, power outages, and a lack of ventilation.
