More than 60 people allegedly linked to a Hispanic street gang have been charged with racketeering and drug trafficking in an indictment that accuses them of attacking blacks in South Los Angeles to maintain control in certain neighborhoods.

Of those under indictment, 34 were arrested during sweeps Tuesday following a three-year investigation, the U.S. Attorney's Office said.

They are suspected members of the Florencia 13 gang, which authorities say is controlled by the Mexican Mafia.

Prosecutors accuse the group of shooting blacks, rival gang members and innocent residents.

"In their attempt to intimidate African Americans in the community, they targeted innocent citizens," U.S. Attorney Thomas P. O'Brien said.

A total of 61 defendants were named in two indictments — one charging violations of federal racketeering laws and the other charging federal narcotics trafficking violations. The indictments were returned by a federal grand jury on Sept. 27 and unsealed Tuesday.

Besides the 34 arrested, some of the others are already in custody or listed as fugitives, authorities said.

Those named in the racketeering indictment face 20 years to life in prison if convicted. The narcotics indictment carries 10 years to life in prison.
