On July 16, 2001 after giving a presentation called "eBooks Security -- Theory and Practice" at the DEF CON convention in Las Vegas, Nevada, he was arrested by the FBI as he was about to return to Moscow, Russia.
The day after his arrest several web sites and mailing lists were started to organize protests against his arrest, many of them under the slogan "Free Dmitry" or "Free Sklyarov". A campaign to boycott Adobe products was also launched.
On July 19, 2001 the Association of American Publishers issued a press release announcing their support of his arrest. Adobe initially supported the arrest, but after a meeting with the Electronic Frontier Foundation, they issued a joint press release on July 23, 2001 recommending his release. However Adobe still supports the case against ElcomSoft.
After Dmitry was arrested he was held briefly in a local jail in Las Vegas; then he was held in the Oklahoma City Federal Prisoner Transfer Center until August 3, 2001, when he was transferred to the Federal building in San Jose, California.
On August 6, 2001 Dmitry was released on a $50,000 bail and was not allowed to leave Northern California. The charges against Dmitry were later dropped in exchange for his testimony. He was allowed to return to Russia on December 13, 2001.
