A man is in custody after officials say he set off an “incendiary device” outside federal buildings in lower Manhattan that house immigration enforcement offices, including ICE and FBI-related operations. Multiple outlets report the incident occurred near the area of 26 Federal Plaza, where an ICE field office and FBI offices are located. Federal officials say the device caused a fire/explosion, prompting emergency response. Reports also say three people were injured, including two firefighters. One source notes the incident affects events connected to immigration proceedings, including the cancellation of a naturalization ceremony and injuries to a person heading to court. Authorities describe the suspect as having prior involvement or history connected to anti-ICE or anti-immigration activity, with some coverage characterizing him as an alleged anti-ICE activist. Another outlet reports the suspect is an Army veteran. The FBI declined to provide detailed information about the suspect’s alleged motivations in at least one account, but says it is investigating the incident. Officials have not indicated any international or broader link, and the man remains in custody as investigators determine the full circumstances.
