A passenger set off firecrackers aboard a plane at Detroit Metropolitan Airport, causing a commotion and some minor injuries, a Delta Airlines official said Friday.
Delta Flight 253, an Airbus 330 carrying 278 passengers, was arriving in Detroit from Amsterdam when the incident took place Friday afternoon, said Delta spokeswoman Susan Elliott.
The passenger was immediately subdued, Elliott said. She had no details on injuries.
An FBI spokeswoman in Detroit said the incident was being investigated.
The pilot reportedly declared an emergency due to a smoke indicator alarm.
The flight landed at 12:01 p.m. ET, 21 minutes later than scheduled, according to the Northwest Web site.
