Attention Members of the Brown Community: The Brown University Public Safety & Emergency Management is investigating an incident that was reported to have occurred on December 12, 2025, at approximately 10:16 AM, on Hope Street in the area of Power Street. In this incident, a Brown University community member reported being approached by a male who identified themselves as a Federal agent, displayed a firearm, and used handcuffs to detain the reporting party. Following the short interaction, the reporting party was allowed to leave the location without further incident. The community member was not physically injured during this incident. At this time, we have not been able to verify with various federal partners that this was an actual federal law enforcement officer; therefore, we are issuing this timely warning The individual who identified themselves as a Federal agent is described as a middle-aged male, approximately 5’10”, bearded, with reddish/brown hair. The individual was further described as wearing a hat, blue jeans, and a black shirt, driving a grey pickup truck. The Providence Police Department is aware of this incident, and Brown Public Safety is cooperating with the Providence Police to investigate this incident. The appropriate campus services were offered to the community member. We ask that anyone who may have been in the area or has additional information about this incident contact the Providence Police Department at 401-272-3121 or the Brown University Public Safety & Emergency Management at 401-863-3322. The Brown University Public Safety encourages the University Community to take the following steps to keep themselves and others safe: • Report suspicious behavior, even when you are not directly threatened. • If you feel unsafe in any situation, trust your instincts and call Brown Public Safety at 401-863-3322 or the Providence Police at 401-272-3121.

TIMELY WARNING UPDATE RE INCIDENT ON HOPE STREET This communication provides an update to the timely warning notice sent earlier today, December 12, 2025, regarding an incident that occurred on Hope Street in the area of Power Street. Following further investigation and coordination with the Providence Police Department (PPD), the Brown University Public Safety & Emergency Management has been able to confirm the identity of the individual who detained a member of the Brown community earlier today. It was a fugitive task force officer who mistakenly identified the community member as a suspect they were searching for. The community member involved in the incident has been informed of this development, and the appropriate campus support services continue to be offered to them. The investigation into the details of the interaction are now being handled by the relevant law enforcement agencies. We continue to encourage the University Community to prioritize personal safety: • Report Suspicious Behavior: Contact Brown Public Safety at 401-863-3322 or the Providence Police at 401-272-3121 if you witness anything that makes you feel unsafe or concerned. • Trust Your Instincts: If you feel unsafe in any situation, remove yourself and call for assistance immediately.

Message elements

How the first alert is built

To check this alert, Claude Opus 5 (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

    Final assessment

    Present, 25 of 25: the message identifies its sender, "The Brown University Public Safety & Emergency Management is investigating an incident", and addresses "Members of the Brown Community".

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardpresent25/25

    Final assessment

    Present, 25 of 25: the hazard is specific, a male who "identified themselves as a Federal agent, displayed a firearm, and used handcuffs to detain the reporting party", possibly an impersonator.

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

  • Locationpresent25/25

    Final assessment

    Present, 25 of 25: the incident is placed "on Hope Street in the area of Power Street", a named intersection just off campus.

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Guidancepresent25/25

    Final assessment

    Present, 25 of 25: the community is told to "Report suspicious behavior, even when you are not directly threatened" and to call Providence Police or Brown Public Safety with information.

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

  • Impactpresent23/25

    Final assessment

    Present, 23 of 25: a man who "displayed a firearm" and handcuffed a community member conveys serious potential harm. The two dissenters weighed the note that the person "was not physically injured".

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
