An example of that Fortean favorite, mysterious showers of stones, appeared in the (Brisbane, Australia) “Courier-Mail” on February 3, 1923:

The police are engaged in investigating a series of mysterious happenings in Albert Square.    About 8 o'clock last night Miss Billie Macdonald was engaged in putting some soda into a lemon squash in the Tivoli Cafe, of which her mother, Mrs. S. Macdonald, is the proprietor, when a small stone fell into the shop through the back door. During the next three hours the mysterious bombardment continued. Later in the evening a customer was struck by a stone, a glass on a table was splintered, and while Miss Macdonald was cooking some eggs in the kitchen she was struck by a stone. The affair became more strange when the attackers piled up rubbish bins at the back door, and when Mr. Macdonald opened the door a stone narrowly missed his head. 

The happenings were assuming alarming proportions, when the assistance of the police was sought. Sergeant Hamilton, assisted by Plain Clothes Constables Wootton and Campbell, and Constables Hird, Burke, Zeller, and Gray commenced investigations. 

The large empty building was at one time occupied by the Green Coupon Tea Company, the windows of which overlook the rear of the shop. came under suspicion. Miss Macdonald was showing the police the way up the back fire escape, when a piece of metal piping fell close to her. Later, when she was with another party of policemen in the Ann-street Presbyterian churchyard, a large stone fell only a few feet away from her. A little pile of large stones was found on a landing at the rear of the Tivoli Theatre, which is next door to the shop. 

Meanwhile, every floor of the premises recently occupied by the Green Coupon Tea Company had been searched. The lift well was pried into, and even the gap between the ceiling and the roof was investigated, but no outlet could be found on to the roof. The police next turned their attention to the Tivoli building, to which the miscreants might have escaped either from the top of the roof or round the back of the building, but up to an early hour this morning no entrance had been made into the building. The throwing of stones ceased at about midnight.

As far as I can tell, the assault on the Tivoli Cafe was a one-off.  I couldn’t find any further reports on the matter.
