Dry ice explosion causes alarm at Los Angeles Airport

The FBI is investigating a dry ice explosion in a restroom at Los Angeles International Airport Sunday evening.

The explosion took place at approximately 7 p.m. local time Sunday in a restroom in the airport's Terminal 2, which is serviced by a number of international airlines, including Air Canada, Air France, Alitalia, KLM, and Virgin Atlantic.

An FBI spokeswoman told the Associated Press that the explosion took place in an employees-only bathroom that was not accessible to the public.

NBC Los Angeles reported that a plastic bottle that had contained the dry ice was discovered by an airport employee who had heard the explosion on the tarmac and gone to investigate.

Flights into and out of the terminal were grounded for approximately 90 minutes before the all-clear was given and normal operations resumed. No injuries were reported.

The Associated Press, citing airport police, reported that at least four flights were delayed as a result of the incident, which caused security screening to be halted.

This is not the first time that a dry ice explosion has occurred at a Southern California landmark. Earlier this year a Disneyland employee was arrested and accused of placing a similar object inside a trashcan at the famous amusement park.
