Tampa-Charges have been filed against a teenage boy who caused an ammonia gas leak in November by drilling a hole into a section of a 30-mile-long pipeline near Tampa. The State Attorneys Office in Hillsborough County released no information on the charges or the young man, because he is a juvenile. The pipeline supplied ammonia to Mosaic’s New Wales phosphate processing plant in Polk County. The youth, who suffered burns from the escaped gas, said he was looking for treasure – which he had been told had been placed there by an armed robber who had committed suicide – buried in the pipe under a bridge crossing the Alafia River.
