BOSTON — Massachusetts State Police are investigating after graffiti was found on the Massachusetts State House on Beacon Hill.

State Police were notified of the graffiti by Department of Conservation and Recreation rangers at about 2 a.m. Sunday.

Troopers responded to the State House and found graffiti on two corners of the building, as well as on a DCR guard building and on a private residence. Police say most of the tagging consisted of words and random letters. The guard house was splashed with paint.

Troopers would not specify what was written with the graffiti in order to preserve the integrity of the investigation.

Police are reviewing surveillance video in the area, which indicates the vandalism was committed Saturday night. Evidence suggests the tagging was likely committed by the same suspect who tagged the State House, other buildings, and a car in the same area earlier this winter.
