Airport policeman arrested

A senior officer in Namibia's airport police has been arrested over the discovery of a suspect package at Windhoek airport that sparked an international alert.

"The arrested man is a high ranking officer at the airport in the police aviation security unit," Namibia's police chief Sebastian Ndeitunga said.

"We don't know yet if that police officer was working alone or in co-operation with other people."

The suspect parcel that was to be put on a Munich-bound charter plane was a harmless United States-made dummy used to test security checks, Germany's Interior Minister Thomas de Maiziere said.
