On October 6, the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) announced sanctions pursuant to the Foreign Narcotics Kingpin Designation Act against four individuals who are allegedly senior members of a Mexican-based drug cartel, which is said to be responsible for trafficking deadly drugs into the U.S. As a result of the sanctions, all property and interests in property subject to U.S. jurisdiction that belong to the sanctioned persons must be blocked and reported to OFAC. U.S. persons are also generally prohibited from engaging in any dealings involving the property or interests in property of blocked or designated persons. OFAC further notes that the designations against the individuals were made in collaboration with the Drug Enforcement Administration and Mexico’s Financial Intelligence Unit.
