Prosecutors say they've charged 11 gang members with multiple murders, attempted murders and other crimes on Long Island.
The defendants were named in a superseding indictment unsealed in federal court in Central Islip on Friday.
Authorities say 10 of the defendants are in custody. The new indictment added five new defendants.
Prosecutors say they are all members and associates of the MS-13 street gang.
The new charges stem from a September 2009 murder of a grocery store worker during an armed robbery in Brentwood. They also include the attempted murder of two rival gang members in Central Islip and seven other armed robberies in Suffolk County between 2009 and 2012.
The superseding indictment includes the charges from the earlier indictment.
