A runaway reindeer broke free from Santa Claus at a Colorado mall Thursday while the Big Man was inside visiting with children.

KYSL in Summit County reports that the reindeer escape happened outside the La Riva Mall in Dillon.

While Santa was inside listening to children’s Christmas wish lists, the reindeer jumped over its enclosure, leading police officers on a healthy jog through town.
