US experts have captured a previous US Marine who is supposedly part of a gathering that attacked North Korea's international safe haven in Madrid, reports state.
Christopher Ahn will apparently show up in a Los Angeles court.
It would be the principal capture over the occurrence, which occurred in February days before US President Donald Trump met North Korea's Kim Jong-un in Vietnam.
Free Joseon, a so called human rights gathering, says it was included.
US government operators have likewise attacked the loft of Adrian Hong, one of the gathering's heads, says the Washington Post.
The US Justice Department did not quickly react to demands for input from the BBC.
In an announcement, Free Joseon said it was "frightened" by capture warrants being executed.
"The last US native who fell into the guardianship of the Kim routine returned home harmed from torment and did not endure," said representative Lee Wolosky.
"We have gotten no affirmations from the US government about the wellbeing and security of the US nationals it is currently focusing on."
