A Brooklyn mom whose terrified 5-year-old was dropped off at the wrong stop is suing the school-bus company for $7 million.\r\nAdrena Hartzog panicked when the bus carrying her daughter, Zariah, never arrived at Flatlands Avenue and 102nd Street.\r\nShe immediately called Leadership Preparatory Ocean Hill Charter School to find out where Zariah was, only to be allegedly left on hold for long stretches.\r\n\u201cEveryone was going home, about their day, while my 5-year-old was missing,\u201d she claimed.\r\nShe called Boro Transit, the company handling the charter school\u2019s transportation. But \u201cnobody had an answer, so I begin to dial 911 and I ran,\u201d the mother recalled.\r\nAfter scouring the neighborhood, she finally found a weeping Zariah, who was so scared she had wet her pants, \u201cscreaming hysterically\u201d more than 10 blocks away at a busy intersection with no crossing guard.\r\nA store owner had offered the child food and called police but Hartzog had arrived before officers.\r\nIn her Brooklyn Supreme Court lawsuit, she claims the bus company refused to take her complaint over the September 2015 incident or even identify the driver.\r\nHartzog, 28, says the company claimed the driver was allowed to drop the child off at an unexpected stop.\r\nAt the time, Boro Transit said the driver was doing \u201ca favor for another parent\u201d by dropping a different child off closer to a grandparent\u2019s home. It\u2019s unclear what other child was involved or how the \u201cfavor\u201d resulted in Zariah being left at the wrong stop.\r\nThe company had no immediate information about the incident, according to Boro Transit lawyer Peter Silverman, who added that the allegations \u201cdo not seem to ring true.\u201d\r\nIt\u2019s a violation of city guidelines for a child to be left at an \u201cunauthorized\u201d stop \u2014 and school-bus drivers face up to a six-month suspension for a first offense.\r\nBut even if the driver had been identified, it might not have mattered. A recent investigation by The Post found school-bus drivers accused of wrongdoing rarely lost their ability to work with city school kids. Records show that between December 2015 and July 2017, at least 281 drivers and escorts endangered kids, but just 32 were fired.\r\nThe mom said the experience \u201cwas beyond terrifying.\u201d\r\nHer lawyer, Stuart Shaw, added, \u201cNo one would cooperate with this woman.\u201d\r\nThe mother of two, who works with the disabled, says her once-bubbly child is now depressed and consistently anxious, and claims her daughter\u2019s classmates ridiculed her after the incident as \u201cthe lost puppy.\u201d\r\nThe Department of Education said it is looking into the incident.
