At least one person over the age of 18 is included in the investigation of a fight between Ridgefield and Wilton students Aug. 31 that sent a Ridgefield football player to the hospital.

There were 10 students from each side involved, with more coming, but the two sides have not been cooperative and much of the information from interviews has contradicted other information, said Lt. Stephen Brennan, spokesman for the Wilton Police Department.

“We’re piecing it together,” Brennan said Tuesday, Sept. 13.

There were reports of a blunt weapon like a bat or golf club used, and the police are not ruling anything out, Brennan said, as the probe continues.

Last week, police reported that a golf club and a bat wasn’t used in the fight.

Wilton police said Friday, Sept. 2, that Ridgefield students went to Wilton High School as part of a “scavenger hunt” where members of a high school senior class participate in pranks and challenges.

One of the items was to urinate on Wilton High’s football field, and that spurred the conflict, according to a source.

“The incident began by Ridgefield High School students coming to Wilton playing a game of scavenger hunt,” said Brennan. “Because the game was publicized, Wilton students were aware that Ridgefield students would be coming to the football field.

“While at the field, an altercation occurred where a Ridgefield student was assaulted,” he said.

Police said the students were from Wilton High School, but could not confirm if they were student athletes.

Wilton Superintendent of Schools Kevin Smith did not return a phone call seeking comment and Wilton High School Principal Robert O’Donnell said in an email to The Bulletin, “The incident remains under investigation and we are cooperating with the Wilton Police Department. I do not want to provide you with any inaccurate or incomplete information as the investigation is ongoing.”

The Wilton Police Youth Division is handling the investigation.

Those with information may call Officer Ross at 203-834-6260.
