An explosion ripped through the Los Angeles County Sheriff’s Department’s Biscailuz Training Academy in East Los Angeles around 7:30 a.m. Friday, killing at least three deputies and injuring another, according to state and local officials. The blast occurred in a parking area of the facility, which serves the department’s Special Enforcement Bureau and arson-explosives detail. Attorney General Pam Bondi called the event a “horrific incident” and said federal agents are assisting. The FBI’s Los Angeles field office, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and Los Angeles Fire Department arson investigators have cordoned off the site while they search for the cause. Early indications point to a possible training accident that occurred as the bomb squad was moving explosives, though authorities emphasized that the investigation is in its initial stages. Governor Gavin Newsom said he has been briefed and offered full state support, while local roads remain closed and the academy has been evacuated. Officials added that there is no immediate threat to the surrounding community. Further details, including the identities of the victims and the exact circumstances of the blast, are expected as the inquiry progresses.
