People across the U.S. expressed outrage on social media after a flag associated with radical Islamic terror groups was found flying outside a Garwood, New Jersey, home. The militant flag, a symbol routinely used by the Islamic State of Iraq and the Levant, has since been taken down “voluntarily,” according to a police spokesperson.

Garwood Police Chief Bruce D. Underhill confirmed in an email to the Washington Free Beacon that his officers are “aware of the situation” and “have taken the appropriate steps.” However, he denied that police “ordered” the resident to take down the flag.

“At this time, the flag in question has been voluntarily taken down. No further comments,” Underhill added.

The flag garnered national attention after a Twitter user posted a photo of the ISIS-associated flag outside the home as well as the resident’s address.

A Turkish flag remains displayed outside the home, but the black militant flag has been replaced with a new flag “that appears to resemble the blue-and-white-stripped flag of Greece,” according to the Free Beacon.

The Islamic militants of ISIS, or ISIL, have been advancing across northern Iraq, leaving a bloody trail in its wake. The radicals ultimately hope to overthrow the Iraqi government, bringing them one step closer to establishing an Islamic caliphate.

Since June, Iraq has been facing an onslaught by the Islamic State group and allied Sunni militants across much of the country’s north and west. In recent weeks, the crisis has worsened as the militant fighters swept over new towns in the north, displacing members of the minority Christian and Yazidi religious communities, and threatening the neighboring Iraqi Kurdish autonomy zone.
