UPDATE: 9:12 a.m. — just learned that Diem was expelled from Lynn University but allegedly returned, was told to leave, then came back. This is the narrative of the report filed by Boca Raton Police. Our original reporting follows:

On 08/23/2022 at approximately 1449 hours I was dispatched to 3601 N Military Trail (Lynn University) (Lynn University) in reference to a white female who was previously expelled by school staff and was now back on campus causing a disturbance. Officer J Cohen and Officer Schuss were also on scene as my back-up officers I met with a Lynn University security guard who told me that he would like to issue an official police trespass warning to a student who returned to campus after being expelled. The security guard stated if she returned to the campus, the staff wish to prosecute. He provided a sworn taped statement that was captured on Officer J Cohen’s MVR and submitted into BRPD evidence.

I then met with a white female who was identified from her student ID as, Alessandria Diem. Diem was verbally issued a trespass warning to leave the property by the security guard in the presence of myself and officer Cohen. She stated she understood and was escorted off the property. At approximately 1510 hours Officer J Cohen and I observed Diem walking back onto the campus. Diem was subsequently placed into handcuffs and advised that she was under arrest for returning to the premise after being warned. Alessandra Diem is being charged with E.s.s 810.097 (2) Trespass on school grounds refused to leave. Diem was transported to BRPD Booking for processing and then transported to the Palm Beach County Jail.

BOCA RATON, FL ( (Copyright © 2022 MetroDesk Media, LLC) — Boca Raton resident Alessandra Diem is facing one count of trespassing on school grounds this morning following her arrest Tuesday evening by the Boca Raton Police Department.

While does not tend to report arrest information without specifics, there is so much concern following the Don Estridge High Tech Middle School student taken into custody Monday for having a knife in his backpack, that any school-related arrest in South Palm Beach County is notable. We expect to have the full details of Diem’s arrest later today.

According to preliminary records reviewed by, Ms. Diem was taken into custody late Tuesday afternoon and booked into the Palm Beach County Jail at 7:41 p.m. She was released early Wednesday morning. It was not immediately clear which school accused her of trespassing, or what transpired before she was arrested. The charge states she “refused to leave.”

Diem’s on social media posts suggest that she was — or is — engaged in a custody battle over a child. It was unclear if that issue is related to her arrest. Court records show Diem was sued for foreclosure by her condominium association earlier this year, but a judge dismissed the complaint.

Diem recently started school at Lynn University, according to her public social media pages.
