Man Arrested at Miami Airport With Blades in Shoe

A man carrying a razor blade and a hacksaw blade in his shoe was arrested at Miami International Airport (search) as he tried to pass through security checks Monday, Miami-Dade police said.

David McIntyre, 38, from Westchester, Pa., was charged with carrying a concealed weapon.

Alarms sounded when McIntyre tried to pass through an airport metal detector at about 6:20 a.m. Airport screeners asked him to remove his shoes and found the blades, officials said.

McIntyre, who was traveling with his wife and children, told authorities he forgot the blades were in his shoe, said Detective Joey Giordano, a spokesman for the Miami-Dade police. It was not known if McIntyre has an attorney.

There was a greater law enforcement presence in the airport given the holiday travel rush, and the Department of Homeland Security's (search) decision to raise the national threat level.

However, officials said they didn't believe this was what led to McIntyre's arrest.
