Premier Daniel Andrews has condemned an international darts tournament at Etihad Stadium that broke into mayhem on Saturday.

Mr Andrews called the behaviour "completely unacceptable" and it was not the type of sporting event Melbourne should be hosting.

"These are not the sort of major events we want in our city and I'm sure that the organisers, those who look after the stadium, everybody in what became very ugly, will sit down and learn from this and be much better prepared, much better equipped when it comes to running similar events in the future," Mr Andrews said.

"This is unacceptable behaviour, we won't tolerate it, we won't stand for it."
