Six Brooklyn men described as members or leaders of a violent gang responsible for five killings and for attempts to kill police officers were indicted yesterday on charges including racketeering and murder, the police and federal prosecutors said.

The charges cover shootings that date to 2000, mostly involving members of rival gangs. One, on Oct. 14, 2001, was directed at a gang member inside a fast-food restaurant in Brownsville; he survived, but the restaurant's manager was killed, according to a statement issued by the United States attorney in Brooklyn, Roslynn R. Mauskopf. The other slaying victims were gang members, prosecutors said. "This is not simply a tale of rival gang members killing each other over turf," John Klochan, the acting assistant director of the F.B.I. in New York, said in a statement. "Nothing gets our attention quicker than conditions that threaten the life and safety of police officers and innocent bystanders."

On Dec. 31, 2002, police officers responding to a call of shots fired in Brownsville were themselves fired upon, and fatally shot two people. Sharief Russell, 25, is charged with attempted murder in that shooting. On June 23, 2000, an off-duty officer was struck and wounded after being caught in the crossfire during a shootout between members of rival gangs; another suspect, Jose Nieves, 23, is charged in that shooting.

The four other suspects are Dwayne Stone, 22, James McTier, 23, Josiah McTier, 28, and Travis Scott, 23. All six defendants pleaded not guilty at their arraignments yesterday in Federal District Court in Brooklyn and were ordered held without bail.
