Security agents allegedly assaulted a Vietnamese-American family at the Tan Son Nhat International Airport in Ho Chi Minh City after they refused to leave Vietnam immediately after being denied entry.

Nguyen Thi Bich Hanh, a former literature teacher, told Radio Free Asia (RFA) about the ordeal she and her children experienced when they arrived in Vietnam on June 7. Hanh, who married freedom of expression activist Thai Van Tu and later settled in the United States, is known for helping Vietnamese students gain a multifaceted and impartial education about Vietnamese Communist leaders. She said that she and her children were taken to a closed room in the airport, where security officers took turns mistreating them.

According to Hanh, airport police requested they board a plane to South Korea to return to the U.S. after they were refused entry. However, she denied the order because one of her sons had severe asthma and was in an emergency situation, and he needed immediate treatment. Tan Son Nhat police authorities called in a doctor, but Hanh said the doctor did nothing to treat her son. Eventually, Hanh had to treat her son with asthma medicine and a ventilator they brought with them from the U.S.

The security officers at Tan Son Nhat International Airport reportedly locked Hanh and her children in a closed room where they could not communicate with their family or anyone outside. Hanh said most of the officers who interrogated them were in plain clothes, so she did not know their names or positions. After two days in custody, the police released them following pressure from the U.S. Consulate in Ho Chi Minh City, and they were made to board a flight to South Korea. The former teacher said she had returned to Vietnam to visit her ailing 89-year-old mother in Nghe An Province.

After RFA reporters contacted Tan Son Nhat Airport authorities to verify Hanh's allegations, a security staff member said on a phone that the information was “incorrect.” According to the person who answered the call, if a person is denied entry to Vietnam, he or she will be deported back to the country where they previously transited before arriving there. The airport staff added that if that person’s name is on a list of dissidents, “immigration security will look into it, but there will be no beatings or arrests.”
