OKLAHOMA CITY (Reuters) -An Oklahoma man was taken into custody after he tried to carry a bomb on board an airplane on Wednesday in Oklahoma City, an FBI spokesman said.

Charles Alfred Dreyling Jr., 24, was detained on Wednesday morning after a security screener using an X-ray machine saw the device in his luggage as he tried to board a flight to Philadelphia at Will Rogers Airport in Oklahoma City.

&#34Although the investigation is in its initial stages we have found no apparent connection to any type of terrorist activity or group,&#34 FBI spokesman Gary Johnson said.

Johnson said the screener saw an &#34improvised explosive device&#34 in Dreyling”s carry-on luggage.

A woman answering the phone at Dreyling”s home on Wednesday night declined to discuss the matter.

Johnson said Dreyling would be charged in federal court on Thursday with possession of an explosive device at an airport.
