U.S. Immigration and Customs Enforcement announced Thursday that Bryan McCarthy was taken into custody at his Deer Park home.
The 32-year-old is accused in a New York federal case of running a website that streamed sports and pay-per-view events illegally and made more than $90,000 from advertisers.
The channelsurfing.net website was seized by federal authorities last month.
Prosecutors say the site pirated telecasts of broadcasts of National Football League games, wrestling matches and ultimate fighting events.
McCarthy's phone number in Deer Park isn't listed. It's unclear if he has an attorney.
A notice on the website last month told users it was seized by "homeland security."
