Families of U.S. citizens murdered by drug gangs in Mexico sued HSBC Holdings Plc, claiming the bank can be held responsible for the deaths because it let cartels launder billions of dollars to operate their businesses.
The lawsuit brings fresh scrutiny to the Mexican activities of HSBC, which in 2012 paid $1.9 billion to resolve a criminal investigation into whether it violated U.S. sanctions laws and laundered at least $881 million on behalf of drug cartels.
HSBC said it would fight the claims in the lawsuit, filed Tuesday in federal court in Brownsville, Texas.
The new case recounts a series of murders in 2010 and 2011 in horrific detail, arguing that the bank should be held to account for them under the U.S. Anti-Terrorism Act.
