Authorities have arrested a passenger they say had a knife in his carry-on bag at Tampa International Airport in Florida.

Philippe Francois Martinez of Clearwater, Fla., was charged Sunday with carrying a concealed weapon. Airport spokeswoman Brenda Geoghagan says Transportation Security Administration workers had initially detained the wrong passenger and bag.

Authorities then reviewed a video showing that the previous passenger to pass through the security checkpoint was the one who had the knife. That passenger, 43-year-old Martinez, had already boarded his American Airlines flight to Miami en route to San Juan, but was detained before the flight took off. It's unclear whether he has an attorney.

No further details were immediately available.
