A former air traffic controller is expected to appear in a federal courtroom in Salt Lake City Thursday, following his arrest last night behind a Wal-Mart in Orem, Utah.
Fifty-four-year-old Robert Burke was wanted on a federal arrest warrant in connection with three explosions outside Grand Junction homes March 24.
Authorities disarmed bombs at two other homes.
A man saying he was Burke's friend called The Daily Sentinel Wednesday, asking a reporter to meet him at noon in Provo, Utah.
But Managing Editor Dennis Herzog says staffers believed the caller was actually Burke himself, and told authorities of the plans.
Burke is accused of placing bombs at the homes of Serco Group employees, and a Federal Aviation Administration worker.
No one was hurt.
