During a routine check of passenger information, Customs and Border Protection officers apparently identified two Sri Lankans carrying Canadian passports that were suspected to be fake, Homeland Security Department spokesman Russ Knocke said.

Authorities placed the pair in custody for questioning, during which the woman became upset, began complaining of chest pains and indicated she needed her bag, which had already been loaded onto the flight, Knocke said.

“There was a significant language barrier with the passengers, and the male is believed to have made a confusing remark about a possible suicide bomb,” Knocke said.
