Two suspicious backpacks found outside Canberra's Lockheed Martin building closed down part of Kingston Tuesday night before being found to contain only a large number of iced coffee containers.
Police reopened part of Wentworth Avenue about 9pm after it was closed earlier on Tuesday night after the suspicious packages were found near the building's entrance.
A police bomb squad was on the scene to assess the situation.
However, police said later the suspicious packages, revealed to be several backpacks, and a number of iced coffee containers found inside one of the bags, had been found to be safe.
Woden Police Sergeant David Perry said investigations were continuing but the containers were not hazardous.
"The bomb technicians have been called and examined the packages and found them to be non-hazardous," he said.
"A number of streets were blocked off while they were examined. Investigations are continuing."
Sergeant Perry said the operation was standard procedure and police "treat all suspicious items very carefully".
The eastbound lane of Wentworth avenue had been closed to traffic between Eyre Street and Dawes Street.

To clarify, the bags being investigated are propped against the Wentworth Ave Lockheed Martin building, not inside #Canberra @canberratimes — Emma Kelly (@EmmaLou_Kelly) March 10, 2015
