PORTLAND, OR,—Sean Michael Davies, 22, a U.S. Citizen residing in Warrenton, Oregon, was arrested this morning after he surrendered to agents of the FBI in connection with charges involving the planting of a fake bomb on a Dutch airliner. Davies is charged in a two-count indictment with making a false report of a destructive device which could damage or destroy an aircraft, and conveying false information about a destructive device which could damage or destroy an aircraft. Both charges carry a maximum penalty of five years in prison and a $250,000 fine.

According to the indictment, on October 20, 2014, Davies was travelling on Flight 569 operated by KLM Royal Dutch Airlines between Amsterdam, Netherlands, and Kilimanjaro and Dar Es Salaam, Tanzania. Davies allegedly constructed what appeared to be a possible bomb or destructive device, hid it in the restroom of the aircraft, and then falsely reported to the flight crew that he had discovered the device, causing KLM Flight 569 to be diverted to Cairo, Egypt.

Davies appeared today before United States Magistrate John Acosta who set the trial on the charges for September 1, 2015, before United States District Judge Michael W. Mosman. Davies is charged in the District of Oregon, as he is a U.S. citizen and a resident of Oregon.

This case was investigated by the FBI with the assistance of authorities in the Netherlands. The prosecution is being handled by Assistant U.S. Attorney Charles F. Gorder, Jr. from the U.S. Attorney’s Office in the Portland, Oregon.

An indictment is only an allegation and not evidence of guilt. Davies is presumed innocent unless and until proven guilty in court.
