Playground slides in Massachusetts vandalized with acid, injuring children.

Two children suffered "burn like" injuries after coming into contact with muriatic acid that had been poured onto playground slides at a park in Massachusetts. The suspects, who may have suffered acid burns themselves, remain at large. The acid had been stored in a secured area in the park's pump room. The playground has been professionally cleaned, but remains fenced off as a precaution. Evidence has been gathered by the Massachusetts State Police crime lab.
