State prosecutors on Monday charged a U.S. Immigration and Customs Enforcement agent with assault in the January shooting of a Venezuelan immigrant in Minneapolis, an incident that sparked violent protests at the height of the Trump administration’s immigration crackdown.

The identity of the agent accused of firing the shot, Christian Castro, 52, had not been disclosed until Monday. Mr. Castro was charged with four counts of second-degree assault, a felony, and one count of falsely reporting a crime, a misdemeanor.

Officials with the Department of Homeland Security did not immediately respond to a request for comment. It was not immediately clear whether Mr. Castro had a lawyer.

A state investigation into the Jan. 14 shooting of the immigrant, Julio C. Sosa-Celis, had been stymied by the refusal of federal agencies to share information, including the names of the two agents involved in a chase that preceded the shooting.

Mr. Sosa-Celis, who was shot in the leg, was one of three people shot by federal agents during the immigration crackdown in Minnesota over the winter. Agents also shot and killed two U.S. citizens in Minneapolis, Renee Good and Alex Pretti.

The Trump administration said the crackdown, known as Operation Metro Surge, would root out illegal immigration and fraud amid insufficient cooperation from state and local officials. Minnesota’s Democratic leaders condemned the campaign as a constitutionally dubious occupation motivated by political animus. Federal judges expressed alarm about some of the administration’s actions.
