The woman walked into the office Friday afternoon and hurled a bottle filled with gasoline and a lit fuse. The fuse disconnected from the bottle and did not ignite, according to the report. Law enforcement officials believe the woman intended to cause harm but the incident wasn’t related to other ones where Homeland Security agencies were targeted.

Ken Cuccinelli, acting director of Citizenship and Immigration Services, which handles legal immigration, said in a tweet that the incident was “another example of the use of violence in place of debate by those who oppose the proper application of our immigration laws.”

Security officers handcuffed the woman who threw the device and she was taken into custody by Federal Protective Service officers who arrested her. Court documents said the incident was also captured on surveillance video.
