Washington, D.C. ? Airport screeners will be taking a closer look at remote control toys in carry-on luggage because of concerns they could be used to detonate bombs, U.S. officials said Monday.

The new practice is a result of reviewing recent intelligence, but isn’t based on any specific threat, according to the Transportation Security Administration.

“We’re always looking at the dots,” TSA Administrator Kip Hawley said Monday. “And we got to the point on this one that we felt it was advisable to alert our officers.”

Airport screeners have been trained for a while on the possibility that remote-controlled toys could detonate bombs, but they have now been told to pay even closer attention.

Authorities recently arrested two Florida engineering students and accused one of them of posting a video online with instructions on how to use a remote-controlled toy to set off a bomb.
