(FOX 11) - A La Habra man has been charged with stalking fifteen women on social media over the last three years.
Orange Country sheriff's investigators say 25-year-old Dominic Magdaleno harassed the women, threatened to sexually assault, rape and even kill them.
They say he targeted them on Twitter, Instagram and Tumblr.
Magdaleno is being held on half-a-million dollars bail after being arrested at the La Habra Public Library last Thursday.
Investigators believe there may be additional victims and are encouraging anyone with information to contact the Orange County Sheriff's Department at (714) 647-7000.
Anonymous tips may also be submitted to Orange County Crime Stoppers at 855-TIP-OCCS.
Some teens and young adults are participating in a growing trend on social media to leave their accounts public in an attempt to become "influencers" a designation determined, in part, by the number of followers an account has.
While this practice is becoming more common, it has the potential to be unsafe.
The Orange County Sheriff's Department offers these tips to ensure safe online practices:
It is best to keep all social media accounts private and only accept friend and follow requests from people you know.
However, if an account is public, do not post any personal identifying information such as your full name, phone number, address, city of residence or school.
Do not tag your current location in photos you post online. This increases your vulnerability and the potential for being the victim of a crime.
Keep it vague. Avoid oversharing personal details of your everyday life and routines.
Monitor comments and messages daily and immediately report any threats of violence.
