OLD ORCHARD BEACH, Maine -- Federal agents attempting to arrest two members of the Outlaws motorcycle gang as part of a seven-state sweep shot and killed one of them in an early morning gunfight Tuesday.

More than two dozen Outlaws gang members across the country were charged Tuesday in Virginia for their roles in violent crimes aimed at gaining the upper hand over rival gangs, officials said.

Bureau of Alcohol, Tobacco, Firearms and Explosives agents were fired upon at about 6 a.m. while attempting to execute arrest and search warrants at a home in this beachside community 10 miles south of Portland, according to ATF spokesman Michael Campbell.

Agents were trying to arrest Thomas "Tomcat" Mayne, 59, the regional treasurer for the Outlaws, on a federal warrant and Kenneth Chretian on a state warrant, Campbell said. He did not identify the deceased, but said Chretian was taken into custody.

Two women were also in the house, but nobody else was injured in the shootout, according to the Maine attorney general's office. Agents found a shotgun and a handgun inside the house after the shooting, authorities said.

Mayne was one of 27 members and associates of the American Outlaw Association motorcycle gang charged in the indictment unsealed Tuesday. A federal grand jury in Richmond, Va., charged many of the defendants with racketeering for allegedly participating in a criminal enterprise involved in attempted murder, kidnapping, extortion, illegal gambling and drug dealing

Defendants are from Wisconsin, Maine, Montana, North Carolina, Tennessee, South Carolina and Virginia. Court records did not indicate that any of them had retained attorneys. Among the defendants is Jack Rosga of Milwaukee, national president of the Outlaws.

The indictment alleges the Outlaws were engaged in violent activities to expand their influence and gain control against rival motorcycle gangs, including the Hell's Angels.

One charge in the indictment alleges that Rosga allegedly directed gang members to retaliate against the Hell's Angels for an attack on Outlaws members, resulting in an alleged murder attempt in Canaan, Maine.
