Find Cambridge Jail Roster Data

Cambridge has no city-run jail. When the Cambridge Police Department makes an arrest, the person is held briefly at the station before being transported to the Middlesex County Sheriff's facility in Billerica. If you are searching the Cambridge jail roster to find someone in custody, you will need to use the Middlesex County inmate locator. This page covers how to use that search, where the county facility is located, how to contact both agencies, and how to request police records from Cambridge PD separately.

Where Cambridge Inmates Are Transferred

Cambridge is part of Middlesex County, and all county custody is managed by the Middlesex County Sheriff's Office. When someone is arrested by Cambridge Police, they are processed at the station lockup for a short period. Once initial processing wraps up, transport to the county facility follows. The Middlesex County correctional facility is at 269 Treble Cove Road in Billerica, MA 01862. That is where Cambridge arrestees go and where you can reach them during their stay in custody.

The Middlesex County Sheriff's Office is a separate agency from the Cambridge Police Department. They handle custody, programming, and inmate records. Cambridge PD handles the arrest and the police side of the case. Both agencies maintain their own record systems, and a request to one does not get you records from the other.

Cambridge is home to Harvard University and the Massachusetts Institute of Technology, which means the Cambridge Police handle a wide range of calls and community contacts. Arrests go through the same county process regardless of who is involved. The county facility in Billerica is the destination for any Cambridge arrest that results in a custody hold.

Middlesex County Inmate Locator

The Middlesex County Sheriff's Office operates an online inmate locator at middlesheriff.com/services/inmate-locator. This is the tool to use when searching the Cambridge jail roster. You can search by name and get back current custody status, booking date, facility, charges, and bail information when available. The database is updated in real time as new bookings and releases happen.

To reach the Middlesex County Sheriff's Office by phone, call (978) 667-0700. Staff can look up someone by name, tell you their current status, and answer questions about the booking process. The full site at middlesheriff.com has information about visiting an inmate, sending mail, commissary, and programs offered at the facility.

Note: Allow a few hours after a Cambridge arrest before searching the county system. The person needs to clear police station processing before being transferred and entered into the county database. If you search right after hearing about an arrest and get no result, try again in a couple of hours or call the sheriff's office to ask.

Cambridge Police Department Records

The Cambridge Police Department is at 125 Sixth Street, Cambridge, MA 02142. The main non-emergency number is (617) 349-9300. The Records Division can be reached at (617) 349-9307. Cambridge PD accepts online records requests through their website. You can also mail or visit in person to submit a request.

Cambridge Police records include arrest reports, incident reports, daily logs, and related documentation. These are city police records and are entirely separate from the county jail roster. If you want to confirm whether an arrest happened, get a copy of the incident report, or verify what was reported to police, contact Cambridge PD. If you want to know where someone is currently held or when they might be released, contact Middlesex County Sheriff.

Public records requests to Cambridge PD are governed by M.G.L. c. 66, § 10. The law gives any person the right to request public records without stating a reason. Most routine requests receive a response within ten business days. If a request is fully or partially denied, the denial must explain which exemption applies.

Cambridge Inmate Roster Record Contents

When you locate someone in the Middlesex County system after a Cambridge arrest, the record will typically show full name, date of birth, booking date and time, current facility, charges entered at booking, bail amount if set, and scheduled court date. Mugshots appear for most bookings. The booking charges are a snapshot of what the arresting officer documented. What ends up filed in court may be slightly different once a prosecutor reviews the case.

Bail status tells you whether someone is being held without bail, has a bail amount set, or has already posted bail. If bail has been posted, the person may be out of custody even though a record still shows in the system. The status field is the key one to check. If the status shows active or in custody, the person is still held. If it shows released or a similar term, they are no longer at the facility.

Cambridge Court and State Inmate Resources

Most criminal cases from Cambridge arrests are heard at Cambridge District Court. Dockets, scheduled hearings, charges, and case status are searchable through MassCourts. Court records and jail records come from two different systems. MassCourts gives you the court side of a case, while the county inmate locator tells you about custody. Both are useful together.

For inmates who have been convicted and transferred to a state prison, use the Massachusetts DOC Inmate Search. The Department of Correction runs the state prison system and maintains a separate public database. Anyone serving a sentence longer than two and a half years typically moves from county to state custody. The county roster will not show them once that transfer happens.

If you need to appeal a records denial, the Massachusetts Public Records Portal has guidance and forms. The Secretary of State's office can step in if an agency is not responding properly to a request.

Additional Cambridge Arrest Resources

Cambridge arrests are processed through a well-established system. Most people held after a Cambridge arrest are at the Middlesex facility in Billerica within several hours. If the county system does not have a record and you believe someone was arrested, start with a call to Cambridge PD to confirm an arrest actually happened, then follow up with the sheriff's office once transport is complete.

For state inmate records or historical criminal information beyond what the county roster shows, the Massachusetts DOC public search and MassCourts together cover most scenarios. The Massachusetts Public Records Portal at mass.gov is an additional resource for navigating records requests and understanding your rights under state law.
