For more than a year, the United States Federal Bureau of Investigation has been hunting the person whom experts say is one of the most prolific swatters in American history. Law enforcement now believes they have finally arrested the person responsible.

A 17-year-old from California is allegedly the swatter known as Torswats, according to sources familiar with the investigation. The teenager is currently in custody and awaiting extradition from California to Seminole County, Florida. The Florida State Attorney's Office tells WIRED that he faces four felony counts.

Seminole County, located in central Florida, had two high-profile swatting incidents within the last 12 months, including one targeting a mosque and another targeting a courthouse. Todd Brown, a spokesperson for Florida's Office of the State Attorney in the 18th Circuit, confirmed the charges against the teen and his extradition. Brown says he will be prosecuted as an adult under Florida law. WIRED is withholding the 17-year-old's name because he is a minor.

The teenager's arrest comes in the midst of a nationwide swatting surge. Swatting attacks typically involve someone calling in fake attacks to 911 in an attempt to solicit an overwhelming police response. Since Christmas, swatters have targeted the homes of prominent politicians from both parties, judges handling cases involving former US president Donald Trump, and the director of the US Cybersecurity and Infrastructure Security Agency.

Prior to these high-profile swats, a relentless campaign from different, potentially foreign, swatting groups targeted hundreds of schools and universities around the US over the past year and a half. Last May, an officer in Danvers, Massachusetts, accidentally fired his service weapon while responding to a school swat. In February, an officer in Saginaw Township, Michigan, rammed his vehicle through the school's locked door to get inside the building following a swatting call.
