BERLIN -- Officials say that a book-sized package delivered to the German embassy in Copenhagen containing "something metallic" turned out to be a scholarship application.

Copenhagen police spokesman Lars-Christian Borg said authorities were alerted Friday after the embassy's mail scanner detected what turned out to be three CDs and an application for a German scholarship program.

Police examined the package for explosives and found it to be harmless.

A package resembling a book and containing an explosive device was sent to German Chancellor Angela Merkel on Tuesday. It was intercepted in the mailroom and defused. No one was injured.
