The FBI has arrested a man accused of sending Dallas reporter Kurt Eichenwald a tweet that triggered an epileptic seizure.

The agency announced that John Rayne Rivello, 29, of Salisbury, Md., was arrested Friday morning in Maryland on a cyberstalking charge.

Eichenwald tweeted that the man who "assaulted" him also is expected to be indicted by the Dallas district attorney on different charges in the next few days.

Eichenwald's attorney, Steven Liberman, told Newsweek that "What Mr. Rivello did with his Twitter message was no different from someone sending a bomb in the mail or sending an envelope filled with anthrax spores."

Eichenwald, a contributing editor at Vanity Fair and a senior writer at Newsweek, first said in December that a Twitter troll sent him a flashing video with the message, "you deserve a seizure," which triggered an epileptic episode.

He received the tweet after appearing on Fox News show Tucker Carlson Tonight, where he and the host argued about each other's biases and Eichenwald's coverage of Donald Trump during the presidential campaign.

According to a criminal complaint, messages sent from Rivello's Twitter account mentioned Eichenwald, saying "I know he has epilepsy," "I hope this sends him into a seizure" and "let's see if he dies."

Authorities also found an screenshot of Eichenwald's Wikipedia page on Rivello's iCloud account, the criminal complaint said, altered to list his date of death as Dec. 16, 2016. Other files on the iCloud account include a list of things that trigger epileptic seizures and a screenshot of a Dallas Observer article about Eichenwald's attempts to find the person who tweeted at him.

Public records show Rivello's most recent address as a home owned by his parents in southeastern Maryland. He has no apparent previous criminal history other than a dismissed speeding ticket.

On Friday, Eichenwald said that more than 40 people sent him strobes once they found out that they could trigger seizures.

FBI spokeswoman Lauren Hagee said the FBI cannot comment on ongoing investigations, but Eichenwald tweeted that the agency has details of the other cases of strobes and urged those people to "stop sending them."
