NEWARK, N.J.— TSA confiscated a cane that had a sharp metal object concealed in it after a man tried to get it past security checkpoint at Newark airport.

Early Thursday morning, a passenger placed their cane onto the checkpoint conveyor at Newark Liberty to go through the x-ray machine.

Transportation Security Administration officers noticed something unusual in the cane’s handle.

Upon further inspection TSA discovered a galvanized piece of metal concealed in the handle of the wooden cane.

The case was deemed non-critical, as the man seemed unaware that the metal was inside the cane.

There have been three arrests at Newark Airport this month for attempting to bring a weapon past security.

On December 23, a TSA agent detected a .45 caliber handgun under the x-ray machine.

On December 19, a loaded .39 caliber handgun was caught in a carry-on bag under the x-ray machine.

On December 5, a loaded .25 was also caught by TSA officers.
