SALT LAKE CITY — An Amtrak passenger was arrested Sunday after police say he made a bomb threat, forcing Amtrak to evacuate one of its passenger rail cars.

Demond Oran Alexander, 45, was booked into the Salt Lake County Jail early Sunday for investigation of making a false alarm, making a terroristic threat and possessing someone else’s ID.

Salt Lake police say the incident happened on an Amtrak train headed to Salt Lake City from Reno. About 20 minutes outside of Salt Lake City, Alexander approached the conductor and dropped a note in front of him, according to a police affidavit.

The conductor picked up the note, which said, “My name is bombman. This train will explode apon arrival,” the affidavit states.

When the train arrived in Salt Lake City, passengers in the car Alexander was sitting in were moved to other cars while a bomb sniffing K-9 from the Utah Transit Authority went through it.

No explosives were found and Alexander was arrested.
