Suspicious devices found in carry-on luggage at the Milwaukee airport play a role in the latest airport alert.
According to a Transportation Security Administration notice dated July 20th, wire coil wrapped around a possible initiator, an electrical switch, batteries, three tubes and two blocks of cheese were discovered June 4th. Cheese can look like certain types of explosives.
The TSA's Lara Uselding won't confirm the finding or the other components found at three other airports in recent months. She says there was no credible threat associated with the notice, just an ongoing effort to remain alert.
The memo does alert TSA officers nation-wide to look out for similar items that could be a practice run for terrorists trying to see what will and will not get through security.
Uselding says it's all part of increased security since 911.
