The Department of Justice has arrested a man they say made death threats against Federal Communications Commission boss Ajit Pai and his family in the wake of the FCC’s repeal of net neutrality regulations.

According to the DOJ affidavit, Pai received three threatening emails in December, shortly after his agency voted to repeal the popular consumer protections. One of those emails expressly threatened the lives of Pai’s children. The threats resulted in Pai canceling his scheduled appearance at CES in January. The first email allegedly attempted to blame Pai for several suicides after the net neutrality repeal. The second email listed the names and addresses of three preschools located near Pai’s Arlington, Virginia home, and said, "I will find your children and I will kill them." According to a press release issued by the DOJ, Markara Man, 33, of Norwalk, California, has been charged with “threatening to murder a member of the immediate family of a U.S. official with the intent to intimidate,” and faces a maximum penalty of 10 years in prison.

The affidavit highlights how it wasn’t particularly difficult for the FBI to track down Man’s identity through his emails, which were reportedly sent from a backup Gmail account.

Federal law enforcement officers confronted Man at his home in May. He admitted sending the emails because he was “angry” about the repeal of net neutrality regulations and wanted to scare Pai.
