STOP TEAM Logo

The Massachusetts State Police STOP Team is a well-trained, disciplined, professional tactical team prepared to respond to any crisis in the New England region. Since 1971 the STOP Team has met this responsibility responding to armed barricaded subjects, hostage situations, serving high-risk warrants, dignitary protection and riot control. The STOP Team has successfully resolved many incidents with other MSP specialized units such as the hostage negotiation team, K-9 Unit, Airwing, SERT Team, Investigation Services and Marine Section.

In addition, the STOP Team continues to provide training and instruction to agencies in response to the active shooter.  The active shooter program was developed and implemented by the STOP Team after the tragic series of school and work place shootings which resulted in mass killing and continues to be a likely threat.
