Parts of Perth’s Murray Street mall have been evacuated following a security scare.

A police spokesman said a suspicious package near Piccadilly Arcade sparked the alert.

There are reports on Twitter that buildings have been evacuated and other people still inside have been told to stay away from the windows.

The City of Perth has recently placed 23 permanent stainless steel bollards at both ends of the Murray and Hay Street malls as precaution against acts of terrorism.

“As there is a high volume of pedestrian traffic through the Murray and Hay Street malls, these were identified as priority areas for enhanced safety measures,” a City of Perth spokesman said earlier this month.

“The City will reassess whether bollards are required in other locations.”

More to come.
