GENERAL CONSIDERATIONS AND GUIDELINES
In order to provide adequate protection to the lives and property of Lexington residents,
it is necessary for the Lexington Police Department to make provisions for augmenting
its resources in emergency situations. The need for additional resources can result
from emergencies such as civil disorders, fires, floods or other disasters. By entering
into cooperative mutual aid agreements with neighboring cities and towns, the
Lexington Police Department will be able to obtain assistance, without delay, to
strengthen our response to emergency situations. This policy further outlines the
procedures for requesting federal law enforcement or National Guard assistance.
In 1992, the Lexington Town Meeting adopted Article 28, which accepted M.G.L.
Chapter 40, section 8G. In pertinent part, this law permits the Town of Lexington to
"enter into an agreement with another city or town...to provide mutual aid programs...to
increase the capability of such departments to protect the lives, safety, and property of
the people in the area designated in the agreement."
PROCEDURES
A. MUTUAL AID AGREEMENTS
1. The Lexington Police Department's mutual aid agreements and Memos of
Understanding will be kept online in the “G drive” and in a 3 ring binder in the
Commanding Officer’s Office and will be labeled Mutual Aid Agreements.
These agreements will include the following information:
a. The legal status of those departments and personnel responding to
a mutual aid request;
b. The legal authority by which responding personnel may act in the
receiving jurisdiction, as provided in M.G.L. Chapter 41, section 99;

f. Procedures for maintaining radio and/or telephone communications
with outside personnel; and
g. Expenditures, if any, which should be borne by the receiving
department to compensate for the use of another department's
resources.
2. Presently, the following communities have Memorandums of
Understanding (MOU) with the Lexington Police Department:
a. An MOU exists creating the Suburban Middlesex County Drug Task
Force. The communities are Lexington, Belmont, Lincoln, Newton,
Watertown, Waltham, Weston, and Arlington. Participating agencies
will be the police departments from each of these communities as
well as the Middlesex County District Attorney, the Massachusetts
Attorney General, The Massachusetts State Police and the Federal
Government (D.E.A., F.B.I., A.T.F., etc. (Dated 18 September 2001)
b. A Mutual Aid Agreement exists between the Lexington Police
Department and the North Eastern Massachusetts Law Enforcement
Council (N.E.M.L.E.C) (Dated 8 September 2003)
c. A MOU exists between the 66SFS at Hanscom and the Towns of
Lexington, Bedford and Lincoln Police regarding the use of a
Drug/Bomb dog. (Dated 15 January 2009)
d. A Massachusetts Interagency Mutual Aid Agreement exists between
the Town of Lexington and all Middlesex County cities and towns
that allows on-duty, sworn police officers to exercise Police Powers
within any of the Middlesex County cities and towns. This
agreement allows sworn police officers from each Middlesex County
city or town to cross into the geographical jurisdiction of any other
city or town to carry out official police business. Such extraterritorial
exercise of police powers is authorized under this agreement in both
mutual-aid-request and self-activation situations.
i. This agreement requires police officers to notify the
commanding officer of the community when they enter to
conduct policing activities.
ii. This agreement is the product of more than a year of
research and work by the Middlesex County Chiefs of Police
Association.
iii. The work stemmed from two Supreme Court Decisions:
Commonwealth v. LeBlanc (1990) and Commonwealth v.
Bartlett (2013). (Dated 18 March 2014)
B. NOTICE TO THE CHIEF OF POLICE
1. The Commanding Officer on duty shall be responsible for notifying the Chief
