JONATHAN ALCORN / AFP via Getty Images The driver of a U-Haul truck that barreled into a crowd at an anti-Iranian regime rally in Los Angeles on Sunday afternoon is in custody. Video from the scene near the federal building in Westwood shows protesters swarming the truck and breaking its windows before police removed a man from the vehicle and took him into custody, the Los Angeles Times reported. Some protesters tried to punch him during the fracas. One person was struck by the U-Haul truck and was treated by a rescue ambulance at the scene, the Los Angeles Police Department told the Daily Beast. No significant injuries have been reported, and no one was transported to the hospital for medical treatment, police said. The incident is under active investigation. L.A. Police Capt. Richard Gabaldon told the Times that authorities believe the incident began after an altercation within the crowd and that it was not politically motivated. The Times reported that the side of the U-Haul said, “NO SHAH. NO REGIME. USA: DON’T REPEAT 1953. NO MULLAH.” Iran has been rocked by nationwide protests against the Islamic Republic’s clerical regime and crippling economic conditions. The regime has governed since the 1979 Islamic Revolution, which overthrew the Iranian Shah, who himself had been installed in 1953 after a CIA-backed coup overthrew a democratically elected prime minister.
