(CNN) -- A five-day operation focusing on foreign-born gang members resulted in the arrests of 105 people in Texas, the U.S. Immigration and Customs Enforcement agency said Monday.
Of those arrested during the operation, which targeted people in the Dallas-Fort Worth area allegedly involved in organized crime, 67 are documented gang members, the agency said, and five are known gang associates. Investigation is under way to determine other suspects' gang involvement.
Seventy-two were arrested on criminal charges, and 33 were arrested on administrative immigration violations, the agency said.
The operation, which ended Saturday, was led by the agency's Office of Homeland Security Investigations National Gang Unit. Those arrested represent at least 29 known gangs, the immigration agency said.
In addition to the arrests, two guns, U.S. currency and drugs were seized, the agency said. It called that consistent with information obtained by the office about north Texas gangs' increasing involvement in narcotics trade and money laundering.
National Gang Unit agents "routinely partner with local law enforcement agencies to target transnational gang members," said John Chakwin Jr., special agent in charge of the Homeland Security Investigations office in Dallas.
The partnerships fall under the umbrella of Operation Community Shield, an initiative meant to minimize the public security threat of transnational gangs.
