A man who prosecutors say lured underage girls he met on a vampire-related Internet site to cemeteries for sex pleaded not guilty to rape and sodomy charges.

Eric Fischer, 23, was ordered held on $350,000 bail after entering the plea Thursday on a 25-count indictment that included charges of rape, criminal sexual act and endangering the welfare of a child, according to the Suffolk County district attorney's office.

Prosecutors said he contacted his victims using a Gothic culture Web site and arranged to meet them in cemeteries on Long Island, east of New York City, prosecutors said.

Fischer was first arrested in March and an incident involving a 16-year-old girl he met on the Web site, police said. A month later, he was accused of luring someone he believed was a 13-year-old girl — but who turned out to be a detective in the Suffolk police computer crimes squad.

Suffolk Assistant District Attorney Julie Walsh said a further investigation uncovered five other potential victims, ranging in age from 14 to 16.

Fischer's attorney, John Ammerman, declined to comment.
