After yesterday's story about "Hack from Hell" Ramez Akladious made headlines, the Taxi and Limousine Commission announced an investigation "into the circumstances of this individual having access to a taxicab while under active license suspensions with the goal of holding the responsible fleets and/or leasing agents fully accountable." Throughout 2008, Akladious still drove cabs despite his suspended license, DWI arrest, and history of violent assaults, including one incident wherein he allegedly slashed a passenger with a box cutter during a dispute over his chosen route. Today the Post has a vivid photo of that man's stitched arm for you; the victim, Kevin Perez of Brooklyn, tells the tabloid, "I saw his face in the paper. I got the chills. It stresses me out to see his face. I didn't take a cab for two to three months after the attack." Sources say Akladious probably hopped from one cab company to another to "try to stay under the radar." Perhaps cab driver Rahmatullah Taher, who was punched in the head by Alkadious during a traffic jam argument last May, put it best: "Worst cabby ever."
