The son of one of two brothers found dead in a country Victorian property has been arrested and remains under police guard in hospital.
Ross Streeter, 30, is the son of Douglas Streeter, who police believe was shot dead along with his brother John Streeter, at their property at Natte Yallock, near Avoca, on Thursday evening.
Mr Streeter was arrested at Avoca in connection with the deaths on Saturday.
Paramedics found him near a water tower in Cambridge Street with self-inflicted injuries, an Ambulance Victoria spokesman said.
The man was taken to Royal Melbourne Hospital in a serious condition under police escort.
Police said the man's injuries were not life-threatening, but he is expected to remain in hospital for at least another day.
He is yet to be interviewed by police.
Police have said it appeared the men, both aged in their 60s, had been shot.
