The United States placed restrictive sanctions on a Mexican oil services subcontractor Wednesday, labelling it an arm of the ultra-violent Los Zetas drug trafficking group.
The US Treasury said Veracruz-based ADT Petroservicios, a longtime subcontractor to state oil company Pemex, was a money-laundering avenue of Los Zetas, one of Mexico's most powerful drug cartels.
The company is controlled by Francisco Antonio Colorado Cessa, who was placed under arrest in the US state of Texas in June after being indicted for laundering Zetas drug money via a US-based horse-racing syndicate.
"By exposing this business of Francisco Antonio Colorado Cessa, which is tied to the violent Los Zetas group, we are depriving their organization of an avenue to launder their illicit proceeds," said Adam Szubin, director of the US Treasury's Office of Foreign Assets Control (OFAC).
"We will continue to target individuals and businesses linked to Los Zetas wherever they attempt to conceal their illegal activities."
The sanctions forbid Americans and American companies from doing any business with ADT.
According to Mexican media, ADT has earned tens of millions of dollars in subcontracts from state oil giant Pemex in the past decade.
