The FBI conducted searches at the Los Angeles Unified School District headquarters and the home of Superintendent Alberto Carvalho on Wednesday, federal officials confirmed.

Agents executed search warrants at both locations as part of what a source familiar with the investigation described to the Associated Press as an "ongoing investigation." The specific allegations being examined remain unclear.

Video footage from local media and citizen reporting apps showed federal agents removing large brown boxes from Carvalho's residence and loading them into FBI vehicles. Officers were also observed entering his office at the school district headquarters.

The Los Angeles Unified School District is the second-largest school district in the United States, making Carvalho's position one of the most high-profile superintendent roles in K-12 education nationwide.

Federal officials have not disclosed the nature of the investigation or provided details about what materials agents were seeking during the searches. Neither the school district nor Carvalho's representatives have issued public statements regarding the federal action.
