The shocking attack happened after the man fought with his wife and physically attacked her, pulling her hair and hitting her repeatedly on the head with the handle of a knife.
The 59-year-old woman sought help from her son and asked him to talk to his father. But this only made things worse, and the father attacked his son, pressing a lit cigarette into his eye - and then running off.
The younger man received first aid and was then treated in hospital. According to a report in the Kronen Zeitung police were able to track down the father and he has since been admitted to a psychiatric institute.
