Up to eight players from the New Zealand Warriors national youth cup side are being investigated by NSW Police after they allegedly trashed a Sydney hotel room hours after being knocked out of the finals.
A police spokeswoman said officers were called to the Holiday Inn at Mascot at 3am on Sunday after receiving reports a number of rooms had been damaged by players in the under-20s side.
Officers then helped staff remove the players from the hotel. Botany Bay police are still investigating.
Warriors chief executive Wayne Scurrah this morning told 2GB radio host Ray Hadley the club had already spoken to the players involved and said their behaviour was "completely unacceptable".
Scurrah said the players had come together in a team room after their loss to the Sydney Roosters and at some stage "breached club policy" when they started drinking alcohol.
"Later on in the evening a small group of them have chosen to go to a couple of rooms and they've - to be blunt - they had a party," Scurrah told Hadley.
"They've continued to consume some alcohol and have a party; they've made an unacceptable amount of noise.
"Certainly they've made a mess. There are some isotonic drink stains on bed spreads, there was a lamp broken and they have generally messed up the room but there has been no walls kicked in or doors broken down."
Scurrah said that the eight players involved would be fined. He has also not ruled out further action being taken.
The Warriors have reimbursed the Holiday Inn for the damage caused and the cleaning bill as well as the guests who were affected by the noise made by the players.
