'You'll be sacked': The stern email sent to every Victorian cop over disturbing trend

Victoria's top cop has issued a warning to all officers on the force after more than a dozen were dismissed over the last year.

You'd expect police officers to be taking action to reduce family violence, predatory behaviour, discrimination, drink driving or drug use - not participating in it.

Chief Commissioner Shane Patton said today he would not tolerate any more inappropriate behaviour as he revealed 17 officers had lost their jobs amid a rise in misconduct and disciplinary hearings.

"To be crystal clear, I sent out a message yesterday and I said if you're engaged in this type of behaviour, this type of conduct, the consequences are you can expect to find the high jump," Patton said.

"You'll be sacked ... unless there's some extreme example which I can't even think of ... the consequences are dismissal."

"We owe that to the public, the vast majority of Victoria Police officers are brilliant and they behave appropriately and with integrity.

"But for those few that very small number of members who think that they won't be held to account, well this message is to them."

The chief commissioner said alarming behaviours like "drink-driving, drug use, family violence, sexual and predatory behaviour, vilifying behaviour including discrimination, homophobia" had been investigated and would not be tolerated.

"The family violence component is a really worrying area where we see members committing family violence," he said.

"Those who we become aware of, we will hold you to account."

It's important those enforcing the law had clear expectations for their behaviour set out, Police Association Victoria Secretary Wayne Gatt said.

"About 99 per cent of our members probably won't even bat an eyelid to be honest because they're out there doing the right thing as you'd expect them to be," he said.

"This is a business-as-usual process that has to be done to set expectations for all police."
