Federal authorities have arrested a suspected accomplice to a man who committed a suicidal terror attack against a California fertility clinic last month.
FBI agents arrested Daniel Park, 32, in New York after he was extradited to the United States from Poland. Authorities say Park provided “significant quantities of ammonium nitrate” to Guy Bartkus, who died bombing a fertility clinic in Palm Springs, California, last month.
“Let this be a reminder: If you harm the American people, or aid and abet those who do, you cannot hide. This FBI will work with our partners to pursue you, find you, and bring you to justice — in any corner of the planet,” FBI Director Kash Patel said in a statement on X.

Attorney General Pam Bondi secured extradition for Park to the United States while she was on a trip to Poland this week. Park had been detained in Poland for two weeks until the attorney general’s visit and his extradition.
“Bringing chaos and violence to a facility that exists to help women and mothers is a particularly cruel, disgusting crime that strikes at the very heart of our shared humanity,” Bondi said in a statement to Axios, which first reported on Park’s extradition.
Bartkus attacked the Palm Springs American Reproductive Centers clinic on May 17. Bartkus drove a car with a bomb inside to the clinic and detonated it, killing himself. Others wounded in the blast have since been treated and released from hospital care.
The blast from the bomb was strong enough to send pieces of nearby vehicles hundreds of feet in the air, according to police.
Park “shares Bartkus’s extremist views,” according to the Department of Justice, which said that Bartkus’ attack was motivated by his “pro-mortalism, anti-natalism, and anti-pro-life ideology.”
Park shipped an estimated 180 pounds of ammonium nitrate, an explosive precursor chemical, to Bartkus ahead of the attack on the clinic. Park also paid for 90 more pounds of the explosive to be shipped to Bartkus, according to prosecutors.
Park began to ship the ammonium nitrate to Bartkus shortly before Park stayed with Bartkus from January 25 to February 8. Park and Bartkus spent part of their time together in Bartkus’ garage “running experiments,” prosecutors said.
