SAN JUAN, Puerto Rico (AP) — A federal grand jury indicted 41 suspected gang members in Puerto Rico accused of smuggling drugs to the U.S mainland as part of a $58 million operation, authorities said Wednesday.

Those arrested include several of the U.S. territory’s suspected drug trafficking leaders, according to Joseph González, special agent in charge of the FBI in San Juan.

He said the suspects are accused of distributing drugs that arrived via ships from Venezuela and the Dominican Republic.

The U.S. Attorney’s Office said the suspects also are accused of distributing heroin, crack, prescription pills and other drugs near various public housing complexes in the capital of San Juan for the past six years.

Three of the 41 suspects are accused of money laundering, including buying cars with revenue from the alleged drug sales.

Authorities said the suspects would prepare the drugs in abandoned apartments in public housing units and stash them in properties using rental applications like AirBnb.
