ST. LUCIE COUNTY — Several sex offenders were arrested after St. Lucie County sheriff’s officials said they didn’t notify authorities they had social media accounts, the agency stated Friday.

Sex offenders every six months must go to the jail, register and reconfirm their address, have their photos taken and make other disclosures, such as whether they have a social media account, a sheriff’s official said. Sexual predators must do so every three months, the official said.
