According to Layton police, officers responded to a report of suspicious activity near 45 East Gentile Street.
Police say the person who made the report said they heard banging on something behind the business.
When officers arrived on scene, police say three young men were seen fleeing on foot.
Police say 18-year-old Michael Corbett and an unnamed 17-year-old boy were quickly apprehended.
After questioning, police say investigators learned that the two young men and another 17-year-old male broke into Costume Castle business, located at 80 West Gentile.
Police say the young men broke a window at the back of the business, got inside, stole masks, swords, and jewelry from inside the store.
