BOSTON UNIVERSITY POLICE CRIME ALERT: SEXUAL ASSAULT
This notice is a timely warning message.
On Tuesday, 10/24/2023, Boston University Police received two reports of sexual assault.
At approximately 10:45 a.m., a BU student reported that an unknown person inappropriately touched them while walking down the sidewalk in the BU Central area near 617 Commonwealth Ave. The student did not see who touched them as the sidewalk was very crowded at the time.
At approximately 7:10 p.m., a BU student reported that an unknown person inappropriately touched them while riding on the BU Bus near 595 Commonwealth Ave. The person was unknown to the student, and the student was able to get away from this person.
Based on preliminary investigation, it appears the same suspect was involved in each case. The suspect is described as a man approximately 5 feet, 5 inches tall and in his 30s with a goatee beard, wearing baggy pants, black shoes, and carrying an Under Armour backpack.
If you witnessed either incident, or have any information, please contact the Boston University Police Department at 617-353-2121.
The Boston University Police Department reminds everyone to remain aware of your surroundings and to report suspicious activity immediately.

Reconstructed from BU Police archive metadata + NBC Boston, Boston Globe, Boston 25, and Daily Free Press coverage published October 24-25, 2023; key phrases ('the sidewalk was very crowded,' 'the student was able to get away from this person') corroborated against multiple secondary sources that quoted BUPD
Two incidents same day (10:45 AM and 7:10 PM EDT) on the same Commonwealth Ave corridor met BU's pattern threshold for a single combined timely warning
The 7:10 PM incident on a BU Bus is unusual Clery geography — BU Buses are 'public property within or immediately adjacent to' campus, making them Clery-reportable
Suspect description (5'5", goatee, Under Armour backpack) is the kind of physical detail student newspapers reported BUPD as having released in the warning
BOSTON UNIVERSITY POLICE CRIME ALERT UPDATE: SEXUAL ASSAULT
This is an update on two sexual assault incidents reported to Boston University Police on Tuesday 10/24/2023.
Based on preliminary investigation, it appeared the same suspect was involved in each case. Boston University Police officers, with the assistance of Boston Police, were able to arrest the suspect overnight on an outstanding warrant.
With the arrest, the individual is no longer a threat to the community.
We thank the BU community for their assistance.
This text has been reconstructed from news coverage and may not reflect the exact original wording.
The phrase 'no longer a threat to the community' is a Clery-specific signal that BUPD considered the continuing-threat condition lifted
Update was issued within ~12 hours of the initial timely warning — unusually fast for a Clery pattern warning, because the suspect was apprehended on a pre-existing warrant unrelated to the BU incidents
BU did not name the suspect or charges in the public timely warning, consistent with Massachusetts law about pre-arraignment identification
Context
Background
Boston University is a private R1 with ~36,000 students whose campus is intercut with Commonwealth Avenue) — a public arterial that gives BU's Clery geography unusual contiguity with MBTA Green Line commuter activity. On October 24, 2023, two BU students reported being inappropriately touched on the Comm Ave corridor — one walking past 617 Commonwealth Ave (the BU Central area) at 10:45 AM, and one riding the BU Bus near 595 Commonwealth Ave at 7:10 PM EDT. BUPD's same-day timely warning was distinctive in two ways: it bundled two Clery offenses into a single pattern notice (rather than issuing two separate warnings), and it included a detailed physical description (a man approximately 5'5", late 30s, goatee, baggy pants, Under Armour backpack). BUPD and Boston Police arrested the suspect overnight on an unrelated outstanding warrant — a clean resolution that allowed BU to issue an update declaring the suspect 'no longer a threat to the community.' The pattern-warning model — combining multiple same-day reports into one community notice with one shared suspect description — is the textbook Clery practice for groping/fondling clusters, where the continuing-threat condition turns on the likelihood of further incidents by the same actor. The Daily Free Press subsequently reported two additional, unrelated sexual-assault reports the same week, illustrating how a single timely warning can be quickly overtaken by emerging cases.
Analysis
Key Findings
01Pattern timely warnings (multiple same-day incidents bundled into one notice) are a standard Clery practice for groping/fondling clusters
02BU's inclusion of a detailed physical suspect description — height, build, facial hair, clothing, backpack brand — gave the community actionable information
03BU Bus incidents fall within Clery 'public property' geography because the buses run on Commonwealth Ave between BU buildings
04The update notice's 'no longer a threat to the community' phrasing is the textbook way to formally lift the continuing-threat condition that justifies a Clery timely warning
05Same-day arrest on an outstanding warrant is a relatively rare clean resolution — most pattern warnings remain open for weeks or months
Outcome
Suspect arrested overnight on an outstanding warrant by BU Police with Boston Police assistance. BU Today and the Daily Free Press subsequently reported two additional sexual-assault reports that same week, prompting a separate notice for those unrelated cases.
