Fire caused $20,000 in damage at a playground in Spanish Fork on Tuesday, April 22, 2014.

SPANISH FORK — Police say three children are responsible for a fire that caused as much as $20,000 in damage Tuesday at Park Elementary in Spanish Fork.

Surveillance footage reveals three children — a girl about 5 or 6 years old, and two 8- to 10-year-old boys — were playing in the school's playground area, 90 N. 600 East. The three started a fire, and, as flames appear on the footage, the children could be seen leaving, Spanish Fork Police Lt. Matt Johnson said.

Winds caused the flames to spread to the school building, where the eaves caught on fire. The rest of the building's brick exterior wasn't affected, although the playground equipment was heavily damaged, Johnson said.

Firefighters were able to suppress the flames Tuesday evening.

Damage to the school building was estimated at $5,000 to $6,000, and damage to the playground equipment was estimated at $10,000 to $15,000 — a total loss, according to investigators.

School administrators were viewing the footage, hoping to identify the children as students at the school, Johnson said.

Asked whether the blaze was deliberate, Johnson said: "That's hard to say at this time."
