Four members of the notorious Armenian Power gang based in California pleaded guilty on September 10 to a host of charges including bank fraud, racketeering and identity theft stemming from a July 2011 indictment.

According to the U.S. Department of Justice, in addition to the gang members, four other individuals linked to the criminal gang also pleaded guilty. All eight are of Armenian extraction.

All told, 70 individuals were charged in the 140-count indictment for criminal activities.

Among the schemes charged in the racketeering indictment is a bank fraud and identity theft scheme that victimized hundreds of customers of 99 Cents Only Stores throughout Southern California. Through the scheme, defendants caused more than $2 million in losses when they secretly installed sophisticated “skimming” devices to steal customer debit card account information at cash registers and then used the skimmed information to create counterfeit debit cards to steal money from victims’ bank accounts.

The case was investigated by the Eurasian Organized Crime Task Force, which is composed of the FBI, the U.S. Secret Service, the Los Angeles Police Department, the Glendale Police Department, the Burbank Police Department, the Internal Revenue Service, and U.S. Immigration and Customs Enforcement-Homeland Security Investigations.

The defendants are scheduled to be sentenced beginning on November 25, 2013. The four gang members face maximum prison sentences of 30 to 102 years.

51 defendants have already pleaded guilty.
