GREENSBORO, N.C. (AP) — Three North Carolina teachers have been arrested and charged with soliciting a minor for sex after a police sting.

Guilford County Sheriff BJ Barnes told a news conference Friday that David Brian Seus, Kevin Samuel and David Frank Pace all thought they were talking to a 13-year-old girl this week. They were actually talking to a deputy.

The 30-year old Seus is a teaching assistant at Western Guilford High School and a lacrosse coach. He was arrested Tuesday and released after posting bond.

Samuel is 46 and teaches at The High School Ahead Academy. He was arrested Thursday and held on a $10,000 bond.

Pace, a 68-year-old teacher in Hendersonville, was being held on a $190,000 bond. Sheriff’s deputies said he communicated with them on several occasions and that more charges against him are possible.
