Three of the four brothers accused of murdering a 45-year-old grill restaurant owner in Thessaloniki, northern Greece, last Sunday were remanded in custody on Wednesday.
A fourth brother, 37, turned himself in to police on Tuesday and will appear before an investigative magistrate on Thursday.
According to investigators, the four brothers – aged 17, 20, 32 and 37 – attacked the victim in his restaurant after he fired the 32-year-old for failing to turn up for work as a delivery driver for several days, claiming he had been injured in an accident.
The 20-year-old suspect has allegedly admitted to stabbing the 45-year-old father of four.
A coroner confirmed that the older man had numerous stab wounds to his chest and stomach, with one of the blows having landed in his heart.
