Police at Los Angeles International Airport are currently investigating how four dry ice bombs ended up in restricted areas of the facility late Monday night. Two of them exploded, though nobody was injured and it caused little disturbance to normal airport operations.
A dry ice bomb is an improvised device in which an airtight container is partially filled with water and dry ice. When the dry ice warms up, the gas inside the container expands until the container bursts.
On Sunday night, a similar bomb was found in a restroom in Terminal 2. According to The Los Angeles Times, "Officials said an airport employee heard an explosion in a men's room and went to investigate. He discovered a 20-ounce plastic bottle that had contained the dry ice. The blast did no damage, and no injuries were reported. "
A detective for the LAPD said that currently their is no clear connection to terrorism. The FBI is assisting in the investigation.
