FORT WAYNE, Ind. (Indiana's NewsCenter) -- Police in Wabash arrested a man for cyber-stalking two sisters -- one of them underage -- and using their identities for sex for two years before he was discovered.

Prosecutors charged the man -- who worked at the family's church -- with felony stalking and misdemeanor harrassment.

Police say he created Facebook pages under the young women's names, then pretended to be them -- posting pictures of them, displaying their addresses and phone numbers, and even detailing their after-school activities and work places.

Using those fake identities, he had virtual sex with men around the world, using language so graphic, we can't share it with you.

The ruse was discovered by their pastor, who was compiling an Internet list of his congregation to take to his new position out of town.

And since their personal information was in cyber-space for two years, the young women now fear for their safety.

Haley Flanagan\Had Identity Assumed:" Me and my sister have both taken a self-defense class. We carry Mace on our keychains with us. And I don't go anywhere by myself."

Cindy Flanagan\Daughters Had Identities Assumed: " These laws need to have some teeth to them, and not just a general law. They need to be substance, they need to be basic enough that it's okay if the Internet changes that they can still apply it to whatever the new technology would be."

The best way to protect yourself and your children? Google your name and see what pops up. If there's anything fishy, call the police.

The man is scheduled to be in court August 20th.

But even if he's convicted of stalking and harrassment, he still wouldn't have to register as a sex offender, which would restrict his Internet use.

That's partly why the family is working with state and federal legislators to draft some stricter laws.
