WICHITA, Kan. (AP) — Federal prosecutors want to shield some evidence in the case of a Wichita man accused of plotting a suicide bombing at Wichita’s Mid-Continent Airport, where he worked as an avionics technician.

A filing Thursday asks the court to limit who can see formerly classified information that has been declassified in order to prosecute 58-year-old Terry Loewen.

Prosecutors allege Loewen tried to get what he believed was a car bomb onto the tarmac on Dec. 13. Charges include attempted use of a weapon of mass destruction and attempted material support to al-Qaida.

The government wants to protect identities of undercover agents and use of sensitive sources and methods.

Prosecutors say Loewen gave the FBI a statement that encompasses five DVDs. It has already disclosed 948 pages of reports and 636 photographs.
