Norwich ― Police are investigating the discovery of two swastikas found spray painted onto the rear wall of Uncas School last week.

Board of Education Chairman Mark Kulos said a school official discovered the graffiti last week, but he said the offensive symbols apparently were old and may have been painted several months ago.

“I don’t know if any of the students saw it,” Kulos said. “It bothers me that the thing is there.”

School maintenance workers painted over the symbols, Kulos said.

Uncas School Resource Officer Jared Homand is investigating. Anyone with information about the graffiti is asked to contact Homand at (860) 886-5561, ext. 3562.

On Feb. 6, Uncas School Principal Peter Camp sent a letter to school staff and parents explaining the incident, stating school custodial staff removed it immediately. Camp provided links to resources parents could use to discuss anti-Semitic hate and violence.

“As educators and members of the community, we are deeply troubled by this discovery,” Camp wrote. “We want to assure you that we take incidents of hate and intolerance very seriously and are taking immediate steps to address the matter.”

Camp wrote that police and school technology officials are examining video surveillance of the area to try to identify the individuals responsible for the graffiti.

Acting Norwich Superintendent Susan Lessard sent a letter to all Norwich staff and parents regarding the incident.

“Let me underscore, hate and intolerance have no place at Norwich Public Schools,” Lessard wrote.
