LaGuardia TSA botches handling of bomb material?

Clueless TSA agents found two possible pipe bombs in a passenger’s luggage yesterday at La Guardia Airport — and kept them in a public area for six hours without notifying cops, The Post has learned.

The Transportation Security Administration bozos at one point left the pipes — which eventually turned out to be harmless — resting on a radiator as hundreds of fliers passed through security nearby, sources said.

“Six hours to report a potential bomb? It’s outrageous,” one Port Authority police official fumed.

The stunning security screw-up, a violation of TSA policy of alerting police to all suspicious activity, began at about 11:30 a.m. at the central terminal when the male flier’s bags passed through an X-ray machine, the sources said.
