The FBI is currently on the hunt for a veteran who is allegedly part of an incident described as an officer ambush at an ICE detention center in Texas on July 4th.

Authorities have identified Benjamin Hanil Song, 32, from Dallas, as the 12th individual involved in last Friday’s attack on Prairieland Detention Center located in Alvarado, Texas.

Song, who once served as a U.S. Marine Corps reservist, faces accusations of using two AR-15 style rifles to shoot at a pair of correctional officers and an Alvarado police officer, as per a criminal complaint mentioned by Fox News Digital.

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

Investigators recovered additional firearms – including another AR-15 style rifle – while searching residences and vehicles. 

Ten assailants are accused of fleeing from the detention center but were apprehended by additional responding law enforcement officers. Song was not located by law enforcement officers, according to the complaint.

The complaint alleges that a white Mercedes-Benz registered to a relative of Song was found two days later in the same block as one of the other assailant’s residences. 

Song is now wanted by the FBI and is considered armed and dangerous. The FBI is offering a $25,000 reward for information leading to his arrest and conviction. 

The ten others charged in the attack are: Cameron Arnold, Savanna Batten, Nathan Baumann, Zachary Evetts, Joy Gibson, Bradford Morris, Maricela Rueda, Seth Sikes, Elizabeth Soto and Ines Soto. 

Another person has been charged with obstruction of justice and conspiracy for attempting to conceal and destroy evidence, prosecutors said.
