Liberian officials say they will prosecute Thomas Eric Duncan, the man who traveled from Liberia to Dallas, because he lied on a form at the airport about having been in contact with the disease, the Associated Press reported.

Duncan had been screened for fever at the airport in Monrovia, Liberia’s capital, and showed no symptoms. But according to reports, he was also required to fill out a form like this one:

According to the AP, Duncan, answered “no” to the questions, even though he had recently helped a sick pregnant woman who later died of Ebola. At the time, though, it was thought she was just suffering from complications from the pregnancy.

A spokeswoman for the consular section of the U.S. Embassy in Monrovia declined to comment to Mashable about Thomas Duncan. Asked if there is any kind of screening process in place for Americans traveling back from Liberia to the U.S., the spokeswoman, who declined to be identified, said: “There is no screening process.” She then hung up the phone.

Duncan “will be prosecuted” when he returns to Liberia, Binyah Kesselly, chairman of the board of directors of the Liberia Airport Authority, told reporters.

He said that people like Duncan and Patrick Sawyer, a Liberian-American with Ebola who traveled to Nigeria and infected people there, have brought a “stigma” upon Liberians living abroad.
