A federal grand jury yesterday indicted a 42-year-old Texas man on a charge of pipe bombing a Fairfax County gynecological clinic last summer in what the grand jury alleged was part of a widespread campaign of violence and intimidation by an antiabortion group called the Army of God.

The six-count indictment filed in U.S. District Court in Alexandria charged Don Benny Anderson with bombing the Arlington-Fairfax Medical Clinic on Arlington Boulevard near Seven Corners and committing other explosives-related offenses.

A woman working in the new clinic was thrown to the ground by the explosion June 6, 1982. The blast caused $10,000 in damage. Four unexploded bombs were found in the clinic afterwards.

Anderson is serving a 30-year sentence in a federal prison on an extortion conviction stemming from the abduction last year of an abortion clinic doctor and his wife in Illinois.

The grand jury also alleged that Anderson conspired with the two other members of the Army of God, Matthew Maxson Moore and Wayne Allen Moore, to make bombs and destroy buildings. The Moore brothers, who were named as unindicted coconspirators, also were convicted in the Illinois abduction case and given lengthy sentences.

In May 1982, the indictment alleged, Anderson and the Moore brothers bombed the St. Petersburg Women's Health Center in St. Petersburg, Fla. At about that time, it said, the three bombed the Bread and Rose Clinic in nearby Clearwater.

After purchasing parts for a bomb, the three went to Falls Church, according to the indictment.

They then went to Illinois and abducted Dr. Hector Zevallos, an officer of the Hope Clinic for Women in Granite City, and his wife, Rosalie Jeanne Zevallos, the grand jury said. The couple was released unharmed after eight days, and the three men were arrested afterward.

If convicted, Anderson faces up to 52 years in prison and fines of up to $70,000.
