A Brooklyn school-bus driver “got lost” for hours on the way home from school and disappeared with several first-graders and kindergarten kids while frantic parents tried to find out what happened. Joseph Gray, 53, was arrested and suspended after he returned to the Achievement First charter school in Brownsville at 9:30 p.m. Tuesday, authorities said. The missing children were unharmed. Gray, a driver for seven years, picked up 23 kids at various stops Tuesday morning without incident, police said. But at the end of the school day, he and the bus disappeared after dropping off most, but not all, of the kids. “I got lost,” he told cops.–NYP
