Hence, we urge those with information about the above cited cases to report them immediately. It is our objective to investigate in order to bring the perpetrators to book," Sergeant Noloyiso Rwexana said in a statement on Thursday.This is after a district social worker whose name has been withheld for security purposes sent an urgent notice to schools within the area in question, in which she warned parents to ensure pupils are dropped off and picked up at the entrance of the school. "Multiple cases have been reported to my office, of learners walking to and from school and being drugged and taken in a van/vehicle," she wrote in the notice.Read: Mother warns pupils after child fights off kidnappersThe Western Cape education department said the urgent notice in question was not meant for wider distribution.
