A TRADIE’S temperature probe, feared to be a possible bomb, has been removed by police after bringing one of Adelaide’s busiest thoroughfares to a lunchtime halt.

Police were called to investigate after reports someone could see wires coming from a grey duct-tape wrapped package near the intersection of Waymouth St and Anster St about noon.

Waymouth St was blocked between Topham Mall and Post Office Lane while the package was investigated, disrupting lunchtime plans for scores of city workers.

Australian Federal Police officers were first on scene, being based in nearby Currie St.

They marshalled people away from the device as cafe regulars sought to get to their favourite spots for coffees, salads and sandwiches.

The AFP officers used chairs to build a temporary barrier as persistent lunchgoers tried to get to Cibo, Jack Greens, The Gallery, Press, Melt and other Waymouth St establishments.

SAPOL officers in cars and paddy wagons arrived at the scene about 15 minutes later, activating flashing lights and erecting tape to block further access.

The AFP officers remained on scene until a SAPOL bomb squad officer arrived in a large white van.

He was spoken to by an Adelaide City Council parking officer for several minutes before putting on his protective suit and walking over to the device.

It took less than a minute for him to lift out what appeared to be a tradie’s temperature probe and place it on the ground.

He returned to his van, spoke to an uniformed sergeant and got out of his suit while the sergeant grabbed a brown paper bag, walked over to the device and put it into the bag.

The identity of the tradie responsible for leaving the device next to Cibo, possibly while he went to get a coffee, is not known.
