Edward Iannone, a former town Board of Finance member, and another Westport man, John Flood, face charges after a fight that was sparked when police said Flood confronted Iannone's 10-year-old son over a prank at the town's annual fireworks show Tuesday night at Compo Beach.

The dispute erupted when Iannone's son threw a water balloon that broke near Flood, police said. After chasing and catching up with the boy, Flood held him against a fence, an incident that later prompted police to charge Flood with second-degree strangulation.

When the boy told Iannone about the incident and pointed out Flood, police said, Iannone approached Flood, who was sitting in his car. Flood admitted to Iannone that he had chased his son and held him against the fence, according to the report.

As the men argued, Flood got out of his car and took a swing at Iannone, police said. The former finance board member backed up and responded by punching Flood in the nose, injuring him, police said.

Flood, 53, of Compo Road South, in addition to second-degree strangulation, was charged with risk of injury to a minor and breach of peace. He was released on $10,000 bond, and is scheduled to appear July 13 in Norwalk Superior Court.

Iannone, 47, of Darbrook Road, was charged with breach of peace and released on a promise to appear July 13 in Norwalk Superior Court.

A graduate of the U.S. Naval Academy, Iannone was a Republican member of the Board of Finance from 2007 to 2011.
