Four more pipe bombs have been found in Canberra after almost a dozen were found on public paths earlier this week.
Police discovered 11 explosive devices in Belconnen in the city's north-west earlier this week after several reports were made to officers.
The devices were seen in the vicinity of Lake Ginninderra between Joynton Smith Drive and Ginninderra Drive.

Today police confirmed they have found and seized a further four pipe bombs in the Belconnen area, which brought the total number of devices discovered to 15.
Officers believe the four pipe bombs are linked to the other 11 devices.
"ACT Policing yesterday cleared the area between Ginninderra Drive and Joynton Smith Drive and will continue to respond to reports of suspected explosive devices as required," police said in a statement earlier this week.
"ACT Policing is urging anyone who locates a suspicious item within the area not to touch it and immediately contact police on triple zero (000).
"Anyone who witnesses suspicious behaviour is urged to contact police on 131 444.
"While there is no information or reports to suggest that these pipe bombs are currently in other parts of Canberra, police are urging any Canberrans to report suspicious items that match the description of a pipe bomb to police."
