An 18-year-old Tampa resident, Oscar Nygard, has been arrested and taken into custody by the Hillsborough County Sheriff’s Office (HCSO) after allegedly posting graphic, violent threats on social media. Law enforcement intercepted Nygard before any physical harm could be carried out, acting swiftly on an anonymous tip.
Incident Overview and Investigation
The arrest unfolded rapidly after a member of the public flagged an extremely alarming post circulating on X (formerly Twitter).
-
The Threat: The digital tip reported that an X account was openly threatening a mass casualty event targeting “little girls at a school.” The suspect explicitly stated his objective was to “set the record for most females killed in a single mass shooting.”
-
The Apprehension: Digital forensics teams within the Hillsborough County Sheriff’s Office quickly traced the IP address and digital footprint of the X account to a residential home in Tampa.
-
The Admission: Upon making contact at the residence, deputies interviewed Nygard, who openly admitted to creating the account and publishing the violent ultimatums.
Legal Status and Response
Nygard is currently facing severe criminal charges related to making written threats to conduct a mass shooting or act of terrorism. While law enforcement has confirmed the investigation remains highly active, they have not yet disclosed whether Nygard had direct access to firearms or a specific target school in mind.
“Threats like this strike fear into our communities and will never be treated as a joke. Thanks to a quick tip and the swift work of our deputies, this individual was identified and taken into custody before anyone could be harmed. If you make violent threats online, we will find you, and you will be held accountable.”
