FLORENCE, Ariz. -- A San Tan Valley man has been accused of sexual assault and sexual misconduct with a minor.
Pinal County Sheriff's officials say 18-year-old Tyler Kost was arrested Monday on suspicion of two counts of sexual assault and two counts of sexual misconduct with a minor.
"It is a vicious criminal who would do this to innocent girls," said Pinal County Sheriff Paul Babeu. "
They say detectives began investigating the case last month and have identified 13 alleged victims, including one girl who is 13 years old.
"One of the victims actually moved out of the state in fear," said Babeu.
Authorities say all of the alleged victims are high school students.
Detectives are continuing to investigate and say more charges are pending.
Sheriff's officials say Kost has been released on a $10,000 bond.
It was unclear Tuesday if he has a lawyer for his case.
