A federal grand jury indicted a Maryland man on one count of stalking after allegedly calling his ex-girlfriend 815 times over 48 hours, according to the Northern District of West Virginia U.S. Attorney's Office.

Derik Wayne Bowers, 44, of Hagerstown, Maryland, is accused of stalking his former girlfriend through text messages, phone calls and Facebook, according to the U.S. Attorney's Office.

"Cyberstalking is a pervasive problem that we treat very seriously in West Virginia," U.S. Attorney William Ihlenfeld said in a Monday statement.
