This bill introduces a new section to RSA 594, allowing private individuals to perform citizen's arrests under specific conditions. A private person may arrest another for a felony or a misdemeanor involving a breach of the peace if the offense occurs in their presence or if they have probable cause to believe a felony has been committed. The bill stipulates that the arrestor must use reasonable and proportional force, promptly notify law enforcement, and only detain the individual until law enforcement arrives. Additionally, it prohibits unauthorized entry onto private property for misdemeanor arrests and allows entry for felony arrests only under exigent circumstances, with immediate reporting to law enforcement.

The bill also provides immunity from criminal or civil liability for private individuals acting in good faith during a citizen's arrest, as long as they comply with the outlined conditions and do not engage in gross negligence or willful misconduct. It mandates that individuals making a citizen's arrest inform the arrested person of their intention and the reason for the arrest. The Department of Safety is tasked with providing public information regarding the regulations and legal risks associated with citizen's arrests. The bill is set to take effect on January 1, 2027, and is expected to incur costs between $100,000 and $500,000 per year for public information campaigns and increased investigative workloads.
