The incident occurred early Saturday morning around 1:30 a.m. local time, involving a broken window and evidence of “minor and limited fire activity.”

Local authorities from the Surprise Police Department initially responded to the scene. The FBI, with assistance from the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), has taken over the investigation.

No arrests have been made, and no suspect information has been released.

The warehouse has been making headlines this month as outraged Democrats attempt to stop its use.

Arizona Democrats like AG Kris Mayes are pushing back against a proposed ICE facility in Surprise. She sent DHS Sec. Kristi Noem a letter seeking answers about plans to convert a 418,000‑square‑foot warehouse into a detention center for 1,500 people.https://t.co/iMCN4Pocpn

This incident follows a separate attempted arson at a Department of Homeland Security (DHS) office in Meridian, Idaho, just days earlier.

In that case, a suspect stole an ambulance and tried to use an accelerant, but was interrupted.

The suspect allegedly stole an ambulance from a bay at St. Luke’s West hospital on Wednesday, drove the ambulance through the parking lot, and retrieved gas cans that were staged in nearby vegetation, according to Meridian Police Chief Tracy Basterrechea.

The suspect, who has not been identified, then drove the ambulance directly into the North Portico building, which houses DHS offices, Basterrechea said.
