SPRINGFIELD – The communications director for Mayor Domenic J. Sarno is accused of damaging property in a restaurant in the MGM Springfield casino and vandalizing vehicles in the facility’s parking garage.

Marian Sullivan, 27, of Springfield, was arrested at about 3 a.m., Sunday, at the casino on the charge of destruction of property. She was booked at the State Police barracks in Springfield and released until her arraignment, said David Procopio, spokesman for the Massachusetts State Police.

State troopers from the on-site Gaming Enforcement Unit were initially called to reports of a woman causing property damage in the Cal Mare restaurant. Subsequently, they learned the woman was in the MGM casino garage and had damaged several vehicles, he said.

“Troopers located the woman in an elevator lobby and observed her to be allegedly intoxicated” and placed her under arrest, Procopio said.

Police did not give specifics on what damage was done or the cost of the vandalism.

Sullivan, who has been the communications director for Mayor Domenic J. Sarno since 2015, was immediately suspended from her job.

“I’m shocked and very disturbed by the arrest of my communications director Ms. Marian Sullivan,” Sarno said in an announcement of her suspension that was released at about 10 a.m.

She will be suspended until the case has gone through the court process, he said. Sullivan is expected to be arraigned in Springfield District Court on Monday.

“I am hopeful that she will seek the help that she seems to need and we will be supportive of that effort,” Sarno said.

Police spokesman Ryan Walsh said the Springfield Police were not involved in the arrest.

Saverio Mancini, director of communications for MGM Springfield declined to comment about the arrest since it is under investigation.
