HIKO, Nev. (AP) - At least two people were detained by local sheriff's deputies at a gate to Area 51 in Nevada after an estimated 75 people gathered at the site early Friday.

  

A weekend gathering is happening in the desert after an internet hoax posted in June invited people to "storm" the once-secret military installation. The place is the focus of popular lore about government studies of extraterrestrial life and space aliens.

  

It wasn't immediately clear if a woman who began ducking under al gate and a man who urinated nearby were arrested after the crowd gathered about 3 a.m.

  

An Associated Press photographer saw both escorted away by deputies. A sheriff's dispatcher declined to comment.

  

Sheriff Kerry Lee was scheduled to speak to the media later in the morning.
