[UPDATE] 12-10 Noon --
A man accused of stalking sorority girls at FSU via Facebook is arrested.
27-year-old Mitchell Hill of Key West is accused of soliciting naked pictures from college girls.
As we reported last week, Hill used a fake name to befriend at least nine FSU students and dozens more from other southern universities and claimed to be an alumni of the sorority. He made threats to many if they did not comply with his requests for naked photos and other personal information. Hill is being charged with video voyeurism and extortion.
Accepting a friend request on Facebook turned into a scary situation for students at Florida State and several other southern universities.
Someone pretending to be an alumni member of several sororities - asked new members private information about themselves and even sent messages claiming that this was 'a very important ritual done by active alumni' and that 'this information is secretive and not to be discussed with anyone."
"People who are coming into a new social environment like a college or university, they want to be accepted, they want to make friends, they want to become involved in organizations and so this person or persons is preying on that need that people have to have a social connection," says Major Jim Russell with FSU PD.
Many students were threatened when they didn't comply with their requests.
An FSU freshman starting her pledge period at Kappa Delta was one of the first to come forward about the incident, only to learn she wasn't the only one being targeted.
Florida State has sent out several crime prevention bulletins since September to all students and parents of the incident and reminded them that "accepting friend requests from strangers may place you at risk."
"It's scary, it's sad, it's frustrating too because with social networking there's no way to control that and Kappa Delta along with all other national sororities we have education programs in place for our membership talking about cyber bullying, hazing and we just have a zero tolerance to all of that," says the national president of Kappa Delta sorority, Beth Langford.
FSU PD says although it's difficult to track down IP addresses or email accounts, it's not impossible. They're working with several other police organizations to track down whoever is behind the harassment.
In the meantime, school officials and police want students to be careful about what information is out there on the Internet because predators can learn a lot about you by what you post.
