WATERTOWN — Police said they have arrested a juvenile in connection with graffiti painted on a playground built in honor of slain Sandy Hook principal Dawn Hochsprung.

The teenager was arrested Tuesday and is scheduled to appear in juvenile court in August, said Detective Mark Conway, public information officer for the Watertown Police Department.

Police were able to link the teen to a distinct style of graffiti found at the playground in Veterans Memorial Park in early February, Conway said Friday. He said it contained a "unique symbol."

The graffiti is believed to be random; it was found at numerous spots in town, including road signs, he said.

"We don't believe that the graffiti is targeting the Sandy Hook cause," Conway said.

Random or not, graffiti is a continuing problem at the playground, he said. Graffiti has been found there this year and in 2022.

"Park and rec cleans the graffiti and eventually more shows up," Conway said.

There are many other unique graffiti symbols, or "tags," that police still are trying to identify, he said.

Officers continue to conduct daily patrol checks of the parks, Conway said.

A group of New Jersey firefighters built the playground in the Nova Scotia Hill Road park in 2014. It was the last of 26 that rose in Connecticut, New York and New Jersey in honor of the 26 children and staff members who died in the Sandy Hook School massacre on Dec. 14, 2012.

The Watertown playground was built in honor of Principal Dawn Lafferty Hochsprung, who was gunned down when she ran out of a meeting to investigate the sounds of gunfire and breaking glass.
