Newcastle's Tyronne Roberts-Davis was not in the photos around the camp but was sprung in the photograph of the group dirt biking.

It comes after NSW Police confirmed on Monday they had fined Mitchell, Addo-Carr and Roberts-Davis $1,000 for the getaway.

The NRL on Tuesday issued four players with breach notices for "bringing the game into disrepute" by flouting social distancing laws amid the coronavirus pandemic.

Mitchell and Addo-Carr have each been handed $50,000 fines, with 60 per cent of that suspended until the end of the season.

Roberts-Davis has been issued with a $10,000 fine, with 60 per cent of that suspended.

In an unrelated matter, Penrith player Nathan Cleary was also fined $10,000 after photographs surfaced of Cleary with a group of people on Anzac Day.

Each player has been handed a one-game ban, however that is also suspended.

The players now have five days to respond to the breach notices.

Australian Rugby League Commission Chairman Peter V'landys said the players were "putting the game and the community at risk by their actions".

"It's certainly hard to accept such behaviour when the game is doing everything it can to persuade the community that its players are responsible and behave appropriately," he said.

NSW Police confirmed they were looking into photographs which appear to show Cleary violating social-distancing rules on the weekend.

Social media photos emerged of him in close contact with a group of several women, reportedly taken at his home on Saturday.

"Police are aware of the images and are investigating," a NSW Police spokeswoman said.

In an Instagram video posted on Monday afternoon, Addo-Carr said that he was "really sorry from the bottom of my heart" and said the getaway was the result of family members "going through a really tough time".

In a separate video, Mitchell also apologised and said the incident had been "a little bit of a slip-up".

"We're not here to break any rules or hurt anyone, we're not being selfish [but] I couldn't turn down the brothers in their time of need," Mitchell said.
