FLORENCE, AZ - An 18-year-old Arizona man accused of being a serial sex predator who allegedly targeted fellow high school students has been re-arrested.
Tyler Kost was originally released on $10,000 bond after being arrested Monday on suspicion of two counts each of sexual assault and sexual misconduct with a minor.
Officials say Pinal County Sheriff's detectives re-arrested Tyler Kost on Thursday on new allegations that include additional cases reported after his initial arrest.
Sheriff Paul Babeu says there are 18 reported victims so far and that other cases may remain unreported.
The office says Kost allegedly threatened to kill victims and witnesses.
An office spokesman was not able to identify Kost's lawyer.
