Police used capsicum spray to subdue a 12-year-old girl in western Victoria at the weekend.

Police were called to a disturbance involving about half a dozen teenagers at Charisma Park in Horsham on Sunday afternoon.

Inspector Trevor Ashton says the girl wrestled with police and threw punches before the officer deployed the OC spray.

The girl is expected to be charged.

Inspector Ashton says he is confident the officers acted appropriately.

"We are presented with all sorts of scenarios, whether they are a 12-year-old male or female. It just depends on their state of mind, the volatility of the situation," he said.

He says it is unfortunate the girl was provocative.

"There will be work done just to make sure that the best practices have been adhered to, and from what I have very quickly witnessed and read, without a doubt they have."
