Pepper spray prompts evacuation

MIAMI -- A Miami International Airport concourse was evacuated for three hours Wednesday after a pepper spray can discharged, causing 43 people to suffer respiratory distress.

The can disguised as a cigarette lighter was found near the second-floor security checkpoint in Concourse B, which serves international flights, a fire department spokesman said.

Officials were certain pepper spray was the irritant, airport spokeswoman Alicia Diaz said.
