He is still recovering from the May 12 incident.
The officer (25) and his partner were patrolling past a Greenwood pool business about 9.30pm, when they noticed a man in a filled swimming pool thumping his head against the side.
Trouble struck when the officers tried to scale a 1.8m barbed wire fence to get to the man.
The probationary constable became entangled in the barbs which suddenly gave way, causing him to fall face first onto the concrete below.
He was knocked unconcious, but quickly recovered to help his partner prevent the mentally-ill man from knocking himself out in the pool.
Warwick police boss Ken Walker commended the officer ” a former member of the military ” for having the resolve to help his partner despite injury.
‘It’s easy to say we do this kind of thing all the time,’ he said.
‘But the outstanding thing for me was the fact that, even though he’s broken his arm and split himself open, he was still there to back his partner up,’ Senior Sergeant Walker said.
The man and the constable were taken to Joondalup Health Campus after the officers had dragged the man from the swimming pool.
