Police station evacuated after cracks appear in walls

An Adelaide police station has been evacuated after cracks appeared in the walls.

The three-storey building in Sturt, south of the city, was cleared after officers hear "a rumble" and saw structural movement in the western end of the site.

"The building is currently closed and will need to be inspected before normal operations can resume," SA Police said in a statement on Wednesday.

Sturt station officers are now working out of neighbouring commands and counter services are being run out of a police operations vehicle in the carpark.
