A federal law enforcement operation in Southern California escalated on Wednesday morning when an agent discharged a firearm during an attempted arrest, according to statements from the Department of Homeland Security.

The incident occurred in Compton, where DHS officers were attempting to take William Eduardo Moran Carballo into custody. DHS identified Carballo as a Salvadoran national with an outstanding final order of removal issued in 2019. The agency said he was also under investigation for alleged involvement in a human smuggling operation and had prior arrests related to domestic violence offenses.

According to DHS, during the arrest attempt, Carballo attempted to flee and used his vehicle to strike law enforcement officers. The agency stated that an officer, believing there was an immediate threat to life and safety, fired defensive shots. Carballo was not hit by gunfire, fled briefly on foot, and was subsequently apprehended.

DHS reported that Carballo was not injured in the incident. A U.S. Customs and Border Protection officer sustained injuries during the encounter. No further details about the officer’s condition were released.

The Los Angeles County Sheriff’s Department confirmed awareness of the incident, noting that deputies provided traffic control in the area but were not directly involved in the arrest operation.

Broader federal investigation

In a separate but related development, the U.S. Department of Justice has issued grand jury subpoenas to several Minnesota state and local officials as part of an investigation into whether public officials improperly interfered with federal immigration enforcement.

Those subpoenaed include Tim Walz, Keith Ellison, Jacob Frey, and officials associated with Ramsey and Hennepin counties. The subpoenas seek documents and communications related to local responses to federal immigration operations, including an enforcement initiative known as Operation Metro Surge.

Minnesota officials have criticized the investigation, describing it as politically motivated. Walz characterized the subpoenas as “political theater,” while Frey said the federal government was using its authority to intimidate local leaders. Federal officials have rejected those characterizations, stating that the investigation concerns potential obstruction of federal law enforcement activities.

Ongoing review

DHS and DOJ officials have emphasized that incidents involving the use of force by federal agents are subject to internal review processes. No conclusions have been announced regarding the Southern California shooting, and authorities have stated that the investigation remains ongoing.

The events reflect a broader national tension between federal immigration enforcement and state and local leadership, with disputes increasingly playing out through courts, subpoenas, and public statements rather than policy negotiation.
