Southern District U.S. Attorney Preet Bharara’s office is prosecuting a man suspected of making bomb threats to Jewish Community Centers to harass his ex-girlfriend under a relatively little-used cyberstalking law generally intended to address intimate partner violence.

Juan Thompson of St. Louis, a former journalist, has been accused of one count of cyberstalking, found under 18 USC § 2261A(2), according to a criminal complaint unsealed on March 3. He faces a maximum penalty of five years in prison.
