Aaron Urbanski was arrested Saturday after authorities were called to a church in Cleburne, which was hosting a 'breakfast with Santa' event.

Police say they found three people demonstrating outside the church after responding to a trespassing complaint.

Authorities say Aaron - who has been booked into the Johnson County Law Enforcement Centre after being charged with criminal trespass - refused to leave and continued to cause a disturbance.

Cleburne's Mayor Scott Cain posted on Facebook, saying ''Don't Mess With Santa!''

The mayor also wrote: ''Guess they wanted coal in their stockings to go with a court appearance.''
