Santiago Lol Tizol, 37, was indicted on one count of interfering with the airline's flight crew. If convicted, he faces 20 years in prison and a $250,000 fine.

Tizol is in custody at the federal detention center near the airport. Tizol, a Guatemalan national who has a brother on the Big Island, was denied supervised release Monday.

FBI agents arrested Tizol soon after Northwest Flight 91 from Los Angeles arrived at Honolulu International Airport at 6:46 p.m. on Dec. 9.

A flight attendant told investigators that Tizol began acting strangely about an hour into the flight, according to a criminal complaint filed in U.S. District Court.

About an hour later, Tizol moved from his seat to the row in front of a Canadian couple and their baby girl, according to an FBI statement.

Several passengers and crew members heard Tizol say he was going to kill the baby and was holding a cell phone cord "in a threatening matter," the affidavit said. Five minutes before the flight was scheduled to land, a flight attendant asked Tizol to move to the back of the plane, but he refused, the affidavit said.

The attendant then moved the Canadian couple and their baby to the back for their safety, the affidavit said. At that point, Tizol allegedly rushed the cockpit.
