A military veteran wanted in connection with an attack on an ICE detention facility in Texas remained on the run Monday, as the FBI’s manhunt stretched into its 10th day.

Benjamin Hanil Song, 32, of Dallas, was named as a suspect on Thursday, almost a week after he allegedly joined a group of 10 to 12 others in an organized attack on officers at the Prairieland Detention Center in Alvarado, Texas, on July 4. Ten assailants were apprehended at the time, though Song managed to evade capture, authorities said.

“We believe he is somewhere in the Dallas-Fort Worth area but have expanded our publicity efforts to neighboring states just in case,” the FBI Dallas Field Office told Fox News Digital on Monday. 

The FBI noted that it is still offering a $25,000 reward for information leading to Song’s arrest and conviction. The bureau previously said Song should be considered armed and dangerous.

The Alvarado police officer was shot in the neck by a suspect in the woods, according to the complaint. Another assailant fired dozens of rounds at unarmed correctional officers who had stepped outside the facility.

The FBI is offering a $25,000 reward for information leading to Song’s arrest and conviction. 

Song faces three counts of attempted murder of a federal officer and three counts of discharging a firearm in furtherance of a crime of violence.
