State Police are investigating an act of vandalism at the Castle Island World War II memorial.
In a statement Monday, agency spokesman David Procopio released details of the troubling incident.
“At approximately 11:30 a.m. today, a caller reported that the World War Two Memorial at Castle Island had been vandalized,” Procopio said. “Troopers responded and discovered a substance – believed to be some type of oil – splashed or poured onto the granite memorial, which is located at the beginning of the causeway heading out to Castle Island.”
He added that “Troop H of the Massachusetts State Police is investigating. The exact time of the vandalism remains part of the ongoing investigation. The state Department of Conservation and Recreation, which oversees Castle Island, was notified and responded in attempt to clean the memorial. Anyone with information about who may be responsible is urged to call State Police-South Boston at 617-740-7710.”
