MIAMI (CBSMiami) – A South Florida swimming instructor who was arrested earlier this week after being accused of fondling two young girls during a swim lesson is now facing an additional charge.

Daniel Diaz-Mejia, 20, was hit with a third count of child molestation after an eight-year-old girl told police that he put his fingers in her swimsuit and fondled her vagina during a lesson.

Diaz-Mejia was originally charged after two 11-year-old girls accused him of doing the same thing.

All three incidents reportedly occurred at the Helen Sands Pool at SW 280st Street and SW 163th Avenue.

During questioning, Diaz-Mejia admitted to the allegations, according to his arrest report.

He remains in jail without bond.
