The Department of Homeland Security said in a statement that a man threw a bottle described as "an improvised incendiary device" at the ICE building on Tuesday evening, October 20. The device struck a perimeter fence and did not reach the facility. No injuries or damage to the building have been reported.
Officials released a photograph of the suspect on Thursday and are asking for the public's help in identifying him. The incident is being investigated as a suspected arson attempt.
The Atlanta attack is at least the fourth time this year that a current or proposed immigration facility has been targeted by a similar fire attack. The DHS statement did not provide details on the other incidents, but the pattern has emerged as the Trump administration accelerates mass deportations, drawing sharp criticism and protest from advocacy groups and some elected officials.
Authorities have not publicly identified a motive for the Atlanta attempt, though the timing and target have fueled concerns about politically motivated violence related to immigration enforcement.
