Police were yesterday investigating the brutal murder of a 32-year-old Thessaloniki taxi driver who was found stabbed to death in his cab in the early hours of Christmas Day. According to a coroner’s report, the unnamed cabbie had been stabbed six times in the neck. His vehicle was discovered in the Pylaia neighborhood. Officers have ruled out the possibility that the unnamed driver was killed during a botched mugging as they discovered that he still had cash on him. Police are also examining the driver’s mobile phone, which was found in the car. They are not ruling out the possibility that this attack was linked to a fatal assault a few weeks ago on a cabbie in the northern city’s Ano Toumba area. As a mark of respect, Thessaloniki taxi drivers did not begin work before 2 p.m. on Boxing Day.
