Three boys will face charges for allegedly stealing a piñata and burning it, thus starting a fire that destroyed a shed containing pole-vaulting equipment at North Medford High School Sunday evening.

Medford police said three boys — ages 11, 9 and 8 — stole food and a piñata from a vehicle parked at the school and took the stolen items inside the shed near the track. They set the piñata on fire and the flames quickly spread, destroying the shed and the foam athletic pads and other equipment in it and sending a pillar of black smoke billowing across the athletic fields. Police said a section of the track was damaged by the blaze.

Investigators believe the 8-year-old and the 11-year-old are responsible for setting the fire. The two boys were charged with second-degree arson, unlawful entry to a vehicle, third-degree theft and third-degree criminal mischief.

The 9-year-old was with them, but didn’t start the fire. He was charged with unlawful entry to a vehicle, third-degree theft and third-degree criminal mischief.

All three boys were cited and released to their parents.
