Authorities arrested a 35-year-old man in connection to the arson attack on Friday at Sen. Bernie Sanders (I-VT) office in Vermont last week.

A justice department release stated that the suspect, Shant Soghomonian, 35, who is also known as Michael Soghomonian, was charged with using fire to damage the building.

Court records show that Soghomonian allegedly entered the building on Friday morning and went to the third floor, where the independent senator’s offices are located.

“Soghomonian was recorded on a security video spraying a liquid near the outer door of the office and then lighting the area with a handheld lighter,” the records noted. “A blaze quickly began while Soghomonian departed via a staircase and damaged the outside of the office door and surrounding areas, and the building sprinklers discharged on multiple floors.”

In a statement, the U.S. Attorney’s Office for the District of Vermont said that the suspect faces a maximum penalty of not less than five years and not more than 20 years in prison and a fine of up to $250,000 if convicted.

Fortunately, Sanders wasn’t in his office when the incident occurred. The senator traveled to Los Angeles to join a picket line where hotel workers were on strike to demand improved pay and working conditions.

In a statement to CNN, the senator expressed his appreciation to experts for their prompt response in putting out the fire.

“I am deeply grateful to the swift, professional, coordinated efforts of local, state, and federal law enforcement in response to the fire at my Vermont office on Friday. I am also thankful that none of the many people in the office building at the time of the fire were injured.”

Burlington Mayor Emma Mulvaney-Stanak appreciated law enforcement and partners’ work in arresting the suspect.

“A special thank you to Burlington Police Department detectives, agents with the Bureau of Alcohol, Tobacco, and Firearms, as well as the U.S. Attorney’s Office for their integral role in bringing swift resolution to this investigation,” Mulvaney-Stanak said. “My office has offered the support of the Burlington Community Justice Center to Senator Sanders’s staff, and we will continue to be in close communication as their office navigates the impacts of this incident.”
