A Pakistani national hospitalized in Athens with massive injuries after crashing a stolen taxi early yesterday is regarded as the main suspect in the stabbing murder and robbery of the taxi’s driver on the capital’s western outskirts. The man, whom police identified as one Mohammed Ali, suffered multiple fractures when he crashed the vehicle belonging to Nikolaos Gialopsos, 42, near the Halyvourgiki Steelworks on the national road from Athens to Corinth. Until late yesterday, he was unable to give testimony to officers who kept him under guard in a KAT hospital ward. Gialopsos’s body was found yesterday morning near Aspropyrgos, a few kilometers west of Athens, with multiple stab wounds. Police believe Ali robbed him after posing as a customer. The taxi driver had been carrying a large sum of money that he had borrowed to build a grave for his son, who died a few weeks ago in an accident.
