Playground slides in Massachusetts doused with acid, injuring children.

Two children suffered burn-like injuries after playing on slides that had been doused with acid at a Massachusetts park. Authorities suspect that someone broke into a storage room where chemicals are kept at the park's swimming pool and stole some muriatic acid. The playground has been cleaned of hazardous materials but remains fenced off. No one has been charged, but authorities said the suspect or suspects may have also been injured.
