Authorities in North Dakota said Wednesday that they have identified an ax-wielding suspect who smashed windows at the office of a Republican U.S. senator. 

Surveillance video showed someone at Sen. John Hoeven’s Fargo office wearing a mask and holding an ax while walking up a staircase toward a door. He smashes a glass window beside the door, taking several swings before walking away.

The vandalism was discovered Monday morning, a spokesperson for Hoeven's office told The Hill.

"We reported it and appreciate the dedicated work of our law enforcement," the spokesperson said.

The Fargo Police Department did not release the suspect's name. 

Calls and messages to Hoeven's office were not immediately returned. The police did not say if an arrest had been made or if one was imminent.
