A YouTuber from the Netherlands in search of Area 51 in the Nevada desert was arrested Tuesday after he and another man entered a secure government area while filming, officials said. The Nye County Sheriff's Office said Ties Granzier, 20, and Govert Charles Wilhelmus Jacob Sweep, 21, were about three miles inside the site before they were detained and questioned by authorities. Located about 65 miles northwest of Las Vegas, and about 10 miles from Area 51, the Nevada National Security Site is a secure area where scientists are known to conduct top-secret nuclear experiments and help secure the country's nuclear deterrent. Inside the men's car, deputies found cameras, a phone, laptop, and a drone, sheriff's officials said in a press release. Granzier and Sweep allowed deputies to review their video, which showed footage from inside the secure area.

The two appeared to be some distance from what is known as Area 51, the famed site that has become synonymous with alleged alien encounters and extraterrestrial conspiracy theorists.

Granzier, who goes by the name "Ties" on YouTube, has more than 730,000 subscribers on the platform. On Tuesday, before he was arrested, Granzier posted a selfie on his Instagram account at the Grand Canyon, telling followers he was headed to Area 51, and included a small alien emoji.
