UPDATE (3 p.m.):

Natrona County Sheriff Gus Holbrook told reporters Tuesday afternoon the suspicious package which caused the airport security checkpoint to be cleared was a refurbished tablet.

"This had wires coming out to a battery," Holbrook said. "They had refurbished it and put in a different battery, so that's why it looked suspicious."

TSA agents reported the suspicious package shortly after 7 a.m. Tuesday after scanning the package with an X-ray machine and seeing the reportedly odd-looking tablet.

The passenger screening area was cleared. Sheriff's office officials and FBI agents were notified.

The sheriff's bomb team responded, confirmed the suspicious nature of the package, and took the package to an off-site location for further examination.

Further assessment revealed the suspicious items attached to the tablet were "homemade foreign electronic components" -- a battery and wiring.

Three people were questioned about the situation for two to three hours. They were later released, Holbrook said.

There was no threat to the public.

Normal flight operations resumed later in the day.
