An official with a union local based in Kansas City was arrested on multiple felony charges last week while attending a conference at Marco Island, Fla.

Scot Albertson, 42, business manager for the International Brotherhood of Boilermakers Local 83, faces charges of aggravated assault, aggravated battery, domestic battery by strangulation and false imprisonment, court records show. He is being held in the Collier County jail in Naples, Fla., with bond set at $400,000.

An attorney for the Boilermakers did not respond to a request for comment Friday. The union’s international headquarters are in Kansas City, Kan.

According to the arrest report, Marco Island police were called to the hotel about 10:50 p.m. last Sunday. A woman told them she had gotten into an argument with Albertson when she tried to look at his phone while they were walking on the beach.

The woman told police that Albertson punched her in the face and that he punched her several more times when they went back to their room, then sat on her chest and choked her. She said he also used a large knife to slice her shirt and threatened to kill her and her children.

Police said they found a “military-type large bayonet” in Albertson’s room. Albertson told them it had been in his luggage the entire time and denied striking the woman.
