A 27-year-old man was arrested on Saturday night on the island of Karpathos after reportedly killing a 68-year-old with a knife.
The alleged suspect barged into the store of the victim located in the village of Pigadia and started stabbing him, state-run news agency ANA-MPA reported.
The store owner was rushed to the local hospital where doctors confirmed his death.
When officers arrived at the scene of the crime, the 27-year-old fled towards the sea and swam to a nearby rocky islet, where he was later apprehended by the coast guard.
According to the report, the suspect is facing serious psychological problems.
