A Namibian police officer has appeared in court on charges related to a fake bomb found in luggage which delayed a flight to Germany last week.
Namibian authorities say they are investigating whether Nehemia Shafuda - who worked in the airport's security unit - had acted alone.
The 51-year-old officer has not yet commented on the charges.
Germany has raised its terrorist threat level, following warnings of an attack planned for the end of November.
Mr Shafuda made a brief appearance in the Windhoek magistrates court, under heavy police guard, says the BBC's Frauke Jensen in Windhoek.
He was whisked away in a van with dark windows under high security.
Journalists were not even allowed to take pictures of the suspect - this has never been a problem in other cases, our correspondent says.
Mr Shafuda is facing charges including contravention of the Aviation and Explosives Act.
"The suspect was identified using CCTV footage. On the footage the suspect was seen handling the parcel," Reuters news agency quotes Deputy Inspector-General Vilio Hifindaka as saying.
His case was postponed to 9 December for bail proceedings.
Despite the media interest in the case, our correspondent says local people are still going about their daily duties as usual.
They agree that it is something that needs to be monitored, but people still feel extremely safe, she says.
Namibia, a large country of just two million people which neighbours South Africa, is a popular destination for tourists from Germany, the former colonial power.
