Cricinfo understands that an incident at the science museum in Adelaide’s south has left staff and visitors “scared”.
It is understood that two people have been taken to hospital after being sprayed with the aerosol at the south end of the museum.
The museum was opened in the early 2000s as part of the City of Adelaide’s redevelopment and is the only one in the country that can be viewed from the main roads.
The incident comes just two weeks after another incident, this time at the South Melbourne Art Gallery, which also involved spraying people.
There is no word on the severity of the injuries sustained in that incident, but police are looking into it.
