Benjamin Song, 32, is wanted by the FBI in connection with an attack on the Fourth of July outside the Prairieland Detention Center in Alvarado.

The suspect, a former U.S. Marine Corps reservist, is accused of joining 11 others in an organized attack against officers at the Prairieland Detention Center.

Nancy Larson, the acting U.S. Attorney, said the planned ambush was not a peaceful protest but was designed to draw ICE personnel outside the facility.

A man charged with tampering with evidence in connection to the ambush on a U.S. Immigration and Customs Enforcement (ICE) detention center in Texas allegedly tried to conceal anti-government and anti-Trump documents.

Authorities are searching for Song in connection with an attack outside a U.S. Immigrations and Customs Enforcement detention facility in Texas on July 4.
