The Dalles Police have made a second arrest related to a fire that melted the curly slide in the Sorosis Park playground area. Police Chief Jay Waterbury says a 15-year-old male was taken into custody on Thursday. He is charged with second degree arson, first degree criminal mischief, and reckless burning. The teen was lodged at the NORCOR juvenile detention facility. Earlier, an 18-year-old man from The Dalles was taken into custody and charged with the same crimes. The fire occurred early in the morning of February 21. Mid-Columbia Fire and Rescue crews arrived to find the ten-foot curly slide fully engulfed in flames. The fire was put out but the slide was completely destroyed. Waterbury said officers interviewed numerous people in an attempt to discover who started the fire, adding the investigation is continuing.
