FARGO, N.D. (AP) — Cass County prosecutors have charged a man accused of using an ax to smash windows at the entrance of North Dakota Senator John Hoeven’s office in the sky way in downtown Fargo.

Court documents show that Thomas Starks, of Lisbon, is charged with criminal mischief, a Class C felony. His first court appearance has not yet been scheduled.

Police identified Starks from security video, where they say he is seen walking up stairs into the sky way to the entrance of Hoeven’s office. The video first shows the suspect striking the secure lock system before striking the windows with the ax. The vandalism was discovered Monday morning. Court documents do not list an attorney for Starks.
