The Tulare County Sheriff's Cyber-Crimes Unit and Central Valley Internet Crimes Against Children Task Force arrested 18-year-old Britney Vasquez of Orosi for the crime.
Detectives say Vasquez created a fake social media account and shared multiple images of underage nude girls.
Vasquez is facing 20 counts of distributing child pornography and is being held on a $1 million bail.
Investigators say they have identified some victims and ask anyone with information to contact the Cyber-Crimes Unit at 559-687-7021.
