The seven people who were allegedly trespassing at the Quabbin Reservoir in Ware early Tuesday are not tied to any other criminal activity, State Police said Thursday. In a statement, spokesman David Procopio said the five men and two women found inside the reservoir were cleared after a “thorough investigation.” Procopio said that “the Massachusetts State Police and the FBI have determined that the subjects have no connection to any other criminal activity or groups. The investigation has determined that the only crime the group committed was trespassing, and there is no evidence that there was a threat to the water supply.”Martin Finucane of the Globe Staff contributed to this report.
