A registered sex offender in Georgetown, South Carolina, was arrested August 19 for allegedly having sex with a 14-year-old and exposing him to HIV, reports NBC affiliate WCBD.

According to authorities, a tip from an anonymous caller led them to the minor. Investigators said that 30-year-old Phillip Wayne Parsons and the 14-year-old have known one another for about a year and a half and that the alleged sex acts occurred in the past several months. Deputies have charged Parsons with criminal sexual conduct with a minor, lewd acts on a minor and exposing another to HIV.

Parsons has been registered as a sex offender in Georgetown County since December 1, 2005, following a conviction of criminal sexual conduct with a minor from January 1, 1995.

He is currently being held at the Georgetown County Detention Center under a $50,000 cash-surety bond.
