A couple who housed a 23-year-old Ukrainian man who was attending a Pennsylvania high school under a fake name say he told them he was much younger, and they deny they took advantage of him.

Stephayne and Michael Potts say Wednesday that they went to authorities because they worried he might hurt fellow students.

The lawyer for Artur Samarin, who attended school as Asher Potts, denies his client made any threats and says everything the Pottses said is "rubbish."

Samarin faces charges of identity theft and statutory sexual assault. He's accused of having sex with a 15-year-old.

Samarin says the Pottses used his illegal status as leverage to make him do work. They say he was merely performing chores.

They haven't been charged with anything.
