Police were called about 6.30pm after a series of alleged intrusions to several homes in the Dawesville street.
It is alleged Mr Bateman went to see what was going on and tried to calm a man down.
Police claim Mr Bateman was confronted by the man and struck with a metal trowel. It is further alleged the two men went inside a neighbouring home, the man armed himself with a kitchen knife and further assaulted Mr Bateman.
Mr Bateman credits his martial arts expertise for saving his life.
‘I was bleeding like mad,’ Mr Bateman said.
‘I’m lucky to be here. I could have been stabbed in the organs.’
Mr Bateman suffered severe injuries to his hands, ribs and neck and was discharged from Royal Perth Hospital on Saturday.
He said the incident had left an imprint on the ‘quiet residential street.’
‘It has shaken and traumatised the area,’ he said.
‘My neighbours are elderly and came here for a quiet retirement. They are thinking of moving, which saddens me.’
Mr Bateman said he was forced to lock his two young children in a bedroom for protection.
‘They didn’t see anything but it has been upsetting for them,’ he said.
A 33-year-old Greenfields man has been charged by police with unlawful wounding and grievous bodily harm.
