By 12:30 PM PST, SFSU issued a shelter-in-place order, instructing anyone on campus to seek a secure location and those off campus to stay away. [Two helicopters and community service officers](https://goldengatexpress.org/109487/campus/live-updates-sfsu-under-lockdown-due-to-emergency-threat/) were deployed to conduct a campus-wide sweep. The shelter-in-place was lifted at 4:18 PM PST after University spokesperson Kent Bravo confirmed no credible threat had been found. The timing during finals week [compounded the disruption](https://goldengatexpress.org/109544/campus/vandalism-identified-as-cause-of-shelter-in-place-order-at-sfsu/), as students with scheduled exams had to coordinate makeup arrangements with their instructors.",
