PORTLAND, Ore. -

FBI agents arrested a 23-year-old man accused of trying to open an emergency exit during his plane's descent into Portland International Airport.
   
FBI spokeswoman Beth Anne Steele says passengers and crew aboard the Alaska Airlines flight from Anchorage to Portland told investigators that Alexander Michael Herrera made "unusual statements" before trying to open the door Monday at about 5:20 a.m.
   
There were no injuries.
   
Steele says Herrera is from Arizona. She does not know his home city.
   
He is being booked into a Portland jail on a charge of interfering with a flight crew and is expected to make his first court appearance Tuesday before a federal magistrate.
