Marines deployed to Los Angeles temporarily detained a civilian on Friday, the U.S. military confirmed after being presented with Reuters images, in the first known detention by active-duty troops deployed there by Donald Trump.

The incident took place at the Wilshire Federal Building in Los Angeles where Marines took charge of the mission to protect the building earlier on Friday, in a rare domestic use of U.S. troops after days of protests over immigration raids.

Reuters images showed Marines apprehending the man, restraining his hands with zip ties and then handing him over to civilians from the Department of Homeland Security.
