A Plano man faces federal charges that he threatened to use deadly force to stop an abortion at a Dallas clinic.
Officials say Lo filed documents in federal court Friday morning saying his religious beliefs entitled him to use deadly force to prevent an abortion.
"My life is at stake," Lo's motion said. "I could be MURDERED AND KILLED as early as Friday, April 2, 2010 at 12:00 p.m. NOON in Dallas, Texas ("TX") if you do not IMMEDIATELY GRANT MY REQUEST for in the very least a TEMPORARY RESTRAINING ORDER!!!"
In the document, Lo was seeking to have abortion declared illegal in the United States.
He threatened to stop an abortion at the Dallas clinic at noon Friday.
"I will try to stop an abortion using oral words, and if words are not enough. I will use physical force if necessary, and if anyone tries to physically stop me, I will overcome that force, and if I must use deadly force to defend the innocent life of another human being, I will," Lo said in the document.
Lo, 27, made an initial appearance Monday in federal court in Plano. His detention hearing was postponed until April 15.
FBI agents arrested Lo on Saturday. He faces one count of using interstate commerce to communicate a threat to injure and one count of threatening force to intimidate and interfere with clients and employees of a reproductive health service.
Federal prosecutors said a man matching Lo's description went to Southwestern Women's Surgery Center about three weeks before filing the court document with a receipt and asked if his wife had an abortion. Clinic employees told the man they could not give out any information about their patients.
A Web site maintained by Lo says he is a Southern Methodist University law school graduate who has taken the New York bar exam.
Lo does not have a listed attorney or phone number.
