Arrest records are public in Cambridge, Massachusetts, pursuant to the Massachusetts Public Records Law (M.G.L. c. 66, § 10). This statute establishes that records generated by government agencies, including those pertaining to arrests made by law enforcement entities, shall be accessible to members of the public. The Commonwealth of Massachusetts maintains this policy to ensure governmental transparency and to uphold citizens' right to information regarding law enforcement activities within their communities. The Cambridge Police Department adheres to these regulations by making non-exempt arrest information available through established protocols.
Public access to arrest records serves multiple civic functions, including enabling community awareness of law enforcement activities, facilitating journalistic reporting on public safety matters, and allowing individuals to verify the accuracy of information pertaining to their own interactions with law enforcement agencies. Certain exceptions to disclosure may apply in cases involving ongoing investigations, juvenile records, or where disclosure would constitute an unwarranted invasion of personal privacy as defined in M.G.L. c. 4, § 7(26)(c).

The Commonwealth of Massachusetts provides legal mechanisms through which eligible individuals may petition for the expungement of arrest records maintained by Cambridge law enforcement agencies. The process is governed by M.G.L. c. 276, § 100E-100U, which establishes specific criteria for expungement eligibility.
Individuals seeking expungement of Cambridge arrest records must file a petition with the court of jurisdiction that handled their case. Eligibility requirements include:
The petition process requires submission of standardized forms to the appropriate court clerk's office. For Cambridge arrests, petitions are typically filed with:
Middlesex County Superior Court
200 Trade Center, Woburn, MA 01801
Phone: (781) 939-2700
Massachusetts Court System
or

Upon successful expungement, all records of the arrest are removed from public access and official databases. Law enforcement agencies, including the Cambridge Police Department, are required to seal or destroy records pursuant to the court order. The legal effect of expungement is to restore the individual to the status they occupied before the arrest, as if it had never occurred.
The Cambridge Police Department maintains compliance with expungement orders through its Records Management System, which flags and removes expunged records from public access and internal searches except as specifically authorized by law.
Massachusetts law imposes significant restrictions on how arrest records may be utilized, particularly in employment and housing contexts. Pursuant to M.G.L. c. 151B, § 4(9), employers are prohibited from inquiring about arrests that did not result in conviction. Additionally, the Massachusetts Criminal Offender Record Information (CORI) Reform Law restricts when and how employers, housing providers, and other entities may access and use criminal history information.
The Cambridge Human Rights Commission, located at 51 Inman Street, 2nd Floor, Cambridge, MA 02139 (Phone: 617-349-4396), provides oversight and enforcement of these protections within city limits. Violations of these provisions may result in civil penalties and administrative sanctions.
