DENVER -- A man was arrested after explosive devices were found in his hotel room at the downtown Denver Sheraton Hotel on Thursday.
Federal law enforcement sources said Adam Hayat, 37, was arrested near Los Angeles International Airport after staying in Denver. He made his first appearance in federal court Friday afternoon.
He has been charged with possession of pipe bombs and will be transported back to Colorado.
"The team immediately notified the Denver Police Department, and they came to investigate,” said Tracy Blair, part of the Sheraton Denver management team.
Police evacuated as many as 20 rooms from the hotel at 1550 Court Place after the bomb squad was called in.
Experts removed several unexploded devices, placing them inside a concrete carrier before taking them away.
"Within a brief, short amount of time, [guests] were given the all-clear for people to return,” Blair said.
Hayat is due in court in Los Angeles. The FBI is investigating why he had the weapons and what he was planning to do with them.
Hayat is an American citizen of Pakistani descent. He had been staying at the Sheraton for perhaps as long as a month.
Reports say he is from the St. Louis area and at one point was in the Marines.
