A dry ice explosion occurred late Monday at Los Angeles International Airport, but there were no reports of any injuries or evacuations, authorities said.
The incident was reported shortly before 8:30 p.m. at the airport's Tom Bradley International Terminal. There was no immediate word where the dry ice was found or whether there was any significant damage.
CBS News affiliate KCAL reported that police later found three more bottles containing dry ice in the Tom Bradley Terminal, all in areas inaccessible to passengers. All of the items were cleared by bomb technicians by 9:45 p.m. local time, according to KCAL.
Investigators don't believe the incident is linked to terrorism and no threat was called into the airport, said Det. Gus Villanueva.
No flights were affected by the explosion, authorities said.
On Sunday night, someone planted a plastic bottle containing dry ice that exploded in an employee bathroom in LAX's terminal 2. Up to four flights were delayed after airport police halted security screening for more than an hour.
No arrests have been made in either case.
A bomb squad was at the airport late Monday and investigators from the LAPD's criminal conspiracy division were assisting, Villanueva said.
