The girl was led into a gymnasium or out into a compound, depending on which story you read, in her uniform where she was bent over a suitable apparatus. The prescribed punishment was then inflicted with both female and male observers present. All versions are agreed that a male police officer or male NCO wielded the cane.
Another story brought to my attention concerns a young Women’s Royal Navy Service (WRNS) officer who began her first posting at a Naval base in the West Country and on her first day was surprised to enter her immediate superior’s (also a WRNS) office door and find a young female trainee bent across the desk being caned on the bottom.
