Sam was issued with a temporary apprehended violence order on Saturday, October 19, after a clash with Mitchell in Bowra.
The British sportsman is thought to have been visiting his children, two-year-old Poppy and 10-month-old Billy, who are believed to have relocated to Bowral with their mother Phoebe after their split.
Mitchell reportedly asked Sam to leave the family's three-hectare Glenquarry farm - which Sam did - but police were called about 4 pm.
It hasn't been a good few weeks for Sam. On Wednesday, he announced his retirement from NRL as a result of a chronic shoulder injury that blighted his 2019 NRL season.
“This decision was one of the hardest decisions I’ve had to make in my life,” he said.
This week, he was also romantically linked with Married At First Sight star Jessika Power, but she has since, sort of, denied those rumours.
On Sunday, leaked footage showed Sam partying on a yacht in Cabo, Mexico, with a bikini-clad woman on his shoulders - despite his shoulder injury. He was there to celebrate the 50th birthday of NRL star Sean Garlick with his brother and fellow rugby player, Luke Burgess.
Earlier this year, Sam split from wife Phoebe three weeks after the birth of his second child Billy Mark. The split came after Sam was cleared of any wrongdoing in the sexting scandal that happened in September when Phoebe was 28 weeks pregnant.
They rekindled their marriage in April, but split again in October.
