A man was grievously injured in a stabbing incident in Zurrieq on Friday, the police said.
An argument between neighbours - two men aged 68 and 27 - ensued in Valley Road at 5pm.
The two ended up in hospital, with the 68-year-old suffering grievous injuries after being stabbed with a pointed instrument while the younger man was unhurt.
Magistrate Franco Agius is leading an inquiry.
