Police have arrested one of Disneyland's own employees after yesterday's dry-ice explosion in the Toontown section of the park, reports the Los Angeles Times. Christian Barnes, a 22-year-old vendor who sold soda and water from a cart, is being held on $1 million bond. Police say he filled a bottle with dry ice and dropped it in a trash can. The ensuing blast caused a lot of noise and chaos, but no injuries or serious damage, reports AP. No word on motive, but police don't think it's related to previous dry-ice bombs in the Anaheim area.
