The Australian government says it is investigating how a classified booklet detailing Barack Obama's itinerary came to be lost in a gutter during the president's visit last week.
Journalist Dylan Welch of The Age newspaper reported that he found the 120-page booklet on Thursday about 100 yards (meters) from Parliament House in Canberra, where Obama attended several functions during his 27-hour Australian visit.
The booklet contained details on Obama's itinerary, his security convoy and the cell phone numbers of senior U.S. and Australian officials.
Australia's Attorney-General's Department said in a statement on Sunday it was investigating. The department said it did not comment on security matters.
