A 37-year-old Brooklyn resident has been arrested for allegedly trying to fight for the Islamic State of Iraq and Syria (ISIS) in Yemen, according to court documents filed Saturday.

Prosecutors say Mohamed Rafik Naji, a citizen of Yemen and legal permanent resident of the U.S., has been expressing support for ISIS on social media since September 2014.

He is alleged to have traveled to Turkey and Yemen between March 22, 2015 and September 9, 2015 in an effort to join ISIS fighting in Yemen.

On July 19th, 2016 in a conversation with a confidential informant, he allegedly expressed support for carrying out attacks in Times Square, similar to the attack in Nice, France.

Officials have long expressed fears about ISIS supporters who appear to be self-radicalized in the U.S. Arrests have been piling up since the rise of the terrorist group in 2014.

NY Governor Cuomo released the following statement following the arrest of Naji:

“The arrest of Mohamed Rafik Naji on charges he provided material support to ISIL is a sharp reminder of the evolving threat of global terrorism. New York must remain vigilant in the face of hate and intolerance, and continue to advance the core values of democracy that this state and nation were founded upon. While we do not have any specific threat at this time, public safety is paramount and we will continue to work aggressively with all local and federal partners. I would like to thank the dedicated professionals at the FBI, US Attorney’s Office for the Eastern District, and state and local police on the Joint Terrorism Task Force for their efforts to keep New Yorkers safe.”
