California State Polytechnic University, Humboldt in Arcata announced it will hold a modified in-person commencement on May 11 after law enforcement regained control of two buildings early Tuesday following a multi-day occupation that prompted a campus lockdown.
More details on the modified commencement schedule will be announced later in the week, the university said.
A shelter in place advisory was implemented by the university this week due to 'criminal activity on campus,' it said in a news release.
Early Tuesday, law enforcement officers cleared and secured two halls -- Siemens Hall and Nelson Hall East -- and arrested 31 people, the university said.
Cal Poly officials lifted the shelter in place order Tuesday afternoon but continued the 'hard closure of campus' until May 10.
'Access to campus is restricted, and individuals are not permitted to enter or be on campus without prior authorization. Supervisors will contact those employees who are authorized to be on campus,' the university said.
