Spera. “Our officers have worked diligently all evening obtaining both search and arrest warrants in an effort to quickly stop these violent attacks against public safety and cause the suspect to be taken into custody.”
State police officials also confirmed they are investigating an intentionally set fire in Roxbury.
The state police fire and explosion investigation unit were requested to 27 North St., also known as the Roxbury Firehouse, according to state police.
