Police are investigating reports of a confrontation at a property in Carroll at about 10.30am on Sunday.

Investigators have been told two men, aged 55 and 60, were involved in a short, physical altercation before the 60-year-old was allegedly pushed to the ground.

Police have been told he was then run over with a quad bike.

The 60-year-old suffered a suspected fractured leg and was taken to Tamworth hospital on Sunday.

He was then airlifted to a Sydney hospital on Monday where he was expected to undergo surgery.

Police have launched an investigation but Oxley Inspector Michael Wurth told Fairfax Media no charges had been laid in relation to the incident.

“The victim has been spoken to by police,” he said.

“A quad bike has been seized from a property in Carroll and investigations are continuing.”
