The former chief executive officer of the nation’s leading supplier of body armor to the American military was indicted yesterday on charges of insider trading, fraud, and tax evasion in a scheme that netted him more than $185 million, prosecutors said.

David Brooks, 53, the founder and former chief executive of DHB Industries Inc., appeared in federal court on Long Island and was ordered held without bail. His lawyer entered a not guilty plea.

“David Brooks grew up in Brooklyn and that means he doesn’t run away from a fight,” his attorney, Paul Shechtman, told reporters after the proceeding.

The charges were outlined in a superseding indictment that also named the former chief operating officer of DHB, Sandra Hatfield, 54. The pair was accused of falsely inflating the value of the inventory of DHB’s top product, the Interceptor vest, to help meet profit margin projections.

The vest, designed to withstand rifle fire and shrapnel, was made for the Marine Corps and other branches of the military.

Last year, Ms. Hatfield and the former chief financial officer, Dawn Schlegel, were indicted on charges of insider trading in the same scheme to inflate the value of the vests. Ms. Hatfield, who was released on $1 million bond in that case, is expected to be arraigned on the new charges next week.

Ms. Hatfield’s lawyer, Roland Riopelle, said the charges announced yesterday are “basically the same” as those in the previous indictment and predicted his client would be acquitted at trial. Mr. Brooks and Ms. Hatfield also are accused of failing to report more than $10 million in bonus payments to themselves and other DHB employees to the IRS. Mr. Brooks also is accused of using DHB funds to buy or lease luxury vehicles for himself and family members, and to pay for vacations, jewelry, cosmetic surgery, country club bills, and family celebrations. Prosecutors say he threw lavish bar and bat mitzvahs for his children in which entertainers like Tom Petty, Aerosmith, and the Eagles performed.
