Alexander Lewis, a teaching assistant at West Florence High School in South Carolina, used a spray he bought online that mimics the smell of faeces. Court documents claim Lewis used the spray repeatedly between August 25 and September 19 which caused disruption to classes, impacted the school’s air system, and sent students to the nurse with respiratory issues. His actions reportedly cost the school about $55,000 (£40,000) for multiple inspections and repairs to its air conditioning system. He was arrested after school CCTV caught him walking through the school’s breezeway with an object in his hand, spraying something before slipping the item into his pocket. Last month Florence County reassured parents that the school’s gas lines, propane systems and air quality were running safely and as normal, Local12 reports.
