A 22-year-old man is due to appear in court on Saturday charged with murdering two brothers in the Perth suburb of Morley.

It is believed the men, all Indian students in their 20s, had an argument over money.

Police say one of the brothers was found dead on Crimea Street about 4:00am Friday.

The other man, who knocked on the door of a St John Ambulance depot pleading for help, later died in hospital.

The 22-year-old man will appear in the East Perth Magistrate's Court charged with two counts of murder.
