A federal judge has issued an order shielding disclosure of government’s evidence against a man accused of plotting a suicide bomb attack at a Kansas airport.

U.S. District Judge Monti Belot on Friday granted the prosecution’s request in the case of Terry Loewen, a 58-year-old avionics technician facing terror-related charges for the alleged plan to attack Mid-Continent Airport in Wichita.

The order covers unclassified materials and information declassified in order to prosecute the case. It allows Loewen to have access only in the presence of his attorney, who must retain possession of evidence.

It also prohibits the government or defense from disseminating evidence to the media, and forbids disclosure of undercover agents’ identities.

Belot further ordered the return of government materials and destruction of defense notes once the case ends.
