INITIAL ALERTTwitter/X
Verified verbatimOfficial @ohionorthern X post (mirrored in ONU Alert SMS, email, and digital signage)242 chars
🚨ONU Alert: A Bomb threat has been received for the ONU campus. We are evacuating the campus. Leave immediately. Do not touch anything and refrain from using your phone. Stay clear. Students, faculty and staff may shelter at Ada High School.
The instruction to 'refrain from using your phone' is unusual but standard bomb-threat protocol: cell signals can in rare cases trigger radio-controlled detonators
Directing the entire campus to a single off-site shelter (Ada High School) is feasible only at very small universities; ONU has approximately 2,900 students total
The order to evacuate everyone simultaneously rather than shelter in place reflects that the threat was non-specific to a single building

Bomb threat has been received. Leave immediately. Evacuate campus. Buses are staging on the Boulevard South of McIntosh to take evacuees to Ada High School. Buildings will be cleared one by one beginning with McIntosh and King Horn.
This is the SMS/text-alert version of the initial 2:16 PM EDT ONU Alert; the X post (seq 1) is the social-media version sent simultaneously with slightly different phrasing
'Buses are staging on the Boulevard South of McIntosh' provides a specific geographic staging point — unusual operational detail for a mass-notification alert
'Buildings will be cleared one by one beginning with McIntosh and King Horn' tells recipients the search order, giving a reassurance timeline not typically found in initial alerts

Verified verbatimOhio Northern University official Facebook page — 5:41 PM EDT Bomb Threat All Clear update on May 5, 2026918 chars
All Clear issued following bomb threat. All ONU buildings have been searched and cleared by law enforcement. Students may return to residence halls and other campus housing. All academic buildings, including Heterick Library and the James Lehr Kennedy Engineering building, will remain closed until Wednesday, May 6 at 7 a.m. Classes and normal business operations, including the Child Development Center, Health Center, and Counseling Center, will resume on Wednesday, May 6 at 8 a.m. The ONU Healthwise Pharmacy will open at 9 a.m. as scheduled. We understand situations like these can be stressful. Assistance is available if you would like to speak to someone. Students may call the Counseling Center to make an appointment or reach out to the Residence Life staff, if they need a listening ear. Faculty and staff may receive support through our Employee Assistance Program by calling 1-888-628-4824 or on the web.
The all-clear was issued at 5:41 PM EDT, approximately three hours and twenty-five minutes after the initial alert, via the Ohio Northern official Facebook page
The opening 'All Clear issued following bomb threat' (not 'ONU Alert:') indicates this is the official website/social statement rather than the SMS version — the SMS may have been shorter
The phased reopening — residence halls that evening, academic buildings until 7 a.m. Wednesday — and the specific counseling resources reflect post-incident community care language standard for campus all-clears
Context

Background

On Tuesday, May 5, 2026, at approximately 1:55 PM EDT, officers were dispatched to Ohio Northern University following a phoned bomb threat to the campus. ONU's first emergency alert was issued around 2:16 PM EDT, directing students, faculty, and staff to leave campus immediately. School officials organized buses near McIntosh Center to transport people to Ada High School, which served as the off-campus shelter. Law enforcement conducted a building-by-building search. By 5:41 PM EDT, ONU issued an all-clear, saying all buildings had been searched and cleared. Residence halls reopened that evening; academic buildings, including Heterick Library and the James Lehr Kennedy Engineering building, remained closed until 7 AM Wednesday. The incident was part of a broader pattern of phoned and emailed bomb threats targeting US universities during the 2025–2026 academic year.
Analysis

Key Findings

ONU's small footprint (about 2,900 students) made a full campus evacuation operationally feasible — a response option unavailable to larger universities
The 'refrain from using your phone' instruction reflects bomb-squad protocol but is rarely seen in larger university alerts, suggesting tight coordination with Ada Police
Total elapsed time from initial alert to all-clear was approximately 3 hours 25 minutes, on the longer end for campus bomb threats but reasonable given the entire campus had to be searched
Outcome
No explosive device was found. Law enforcement searched and cleared every building on campus. Residence halls reopened the evening of May 5, while academic buildings, including Heterick Library and the James Lehr Kennedy Engineering building, remained closed until 7 AM the next day. Classes resumed Wednesday, May 6 at 8 AM.
