Two of the men took off, but one had another crack at a senior constable, who was responding to reports of a public nuisance.
One of the men charged over the incident was 34-year-old Levi Hilton.
The court heard Hilton became violent when he saw his younger brother being arrested, and was upset that police were restraining him by the neck.
“He’s very happy to have this behind him, obviously he’s extremely remorseful,” his lawyer said.
He pleaded guilty to three counts of assault, one against Paramedic Adam Flory.
“We’re here to help you. We’re not here to harm you, but we don’t want to be harmed while doing our job as well,” Flory said.
Hilton was sentenced to nine months’ jail but immediately released on parole.
