Bangkok  - Thai police arrested a female teacher for having sex with a 13-year-old boy whom she was tutoring in her room, media reports said Tuesday.

Police arrested Thanawan Klongsinchai, a 29-year-old English teacher, Monday on charges of molesting a minor, the Khao Sod newspaper said.

Thanawan denied the charge, claiming the sex was consensual.

Parents of the 13-year-old, who was big for his age group, pressed charges against the teacher after the boy told his friends of the affair, the newspaper said.

Thanawan had been providing the boy private tutorials in English in her school dormitory, where the alleged harassment took place. She claimed the boy made the first moves and she eventually consented. (dpa)
