Milo to be billed $50,000 for police operations

Controversial British commentator Milo Yiannopoulos and his promoters will be asked to cough up at least $50,000 to cover the heavy police presence at his Melbourne event.

Hundreds of police were sent in to control up to 500 left-wing and up to 50 right-wing activists who clashed violently outside Yiannopoulos' Kensington event on Monday night.

Five officers were pelted with bottles and rocks and two protesters, one from each side, were arrested.

Police Minister Lisa Neville said the event's organisers would be sent a bill for at least $50,000 to cover the police presence.

She said it was a standard practice for these kinds of events.

"I'm not sure whether they have (agreed to pay it) but they will certainly be getting a bill for it," Ms Neville told 3AW last night.

Organisers for Yiannopoulos' Australian tour previously said they expected to be billed about $150,000 for the police presence.
