Please be advised that the Ann Arbor Police Department is investigating three assaults against women that occurred in downtown Ann Arbor between Friday, July 16 and Sunday, July 18. Police believe these assaults may have been committed by the same individual.

In response to the incidents, Ann Arbor Police and the U-M Police Department have increased patrols during the night while Ann Arbor police detectives continue their investigation.

Michigan Medicine also has additional officers patrolling on bikes and in vehicles as another layer of security.

Residents and visitors in Ann Arbor are advised to be extra vigilant and aware of their surroundings when walking around at night.

 Here are a few tips to help you stay as safe as possible: 

  • Look assertive and trust your intuition. If a particular situation makes you feel uncomfortable or unsafe, choose an alternative. We also recommend walking with a friend or co-worker in well-lit areas and avoiding isolated areas.
  • For U-M students, faculty and staff, be sure to check out the university’s after-hours transportation options. If you choose to utilize non-university rideshare options, be sure to know how to do so safely by reviewing this safety tips page.
  • If you feel threatened, look for a blue light emergency phone on campus or call 911 from any phone.
  • If you see something, say something: Report suspicious behavior by calling 911.

 Anyone with information about any of the incidents is asked to contact Det. Sgt. Dawn Murphy at 734-794-6930, Ext. 49302 or or by calling the anonymous tip line at 734-794-6939 or emailing
