HARRISBURG- Harrisburg police on Friday charged a 23-year-old Ukrainian national who was arrested for posing as a Harrisburg high school student with two sex crimes.

Police charged Artur Samarin with statutory sexual assault and corruption of minors, both felonies. The charges stem from a relationship Samarin reportedly had with a 15-year-old girl in 2014 when Samarin was 22-years-old.

Immediately after Samarin was outed as a 23-year-old man on Tuesday instead of an 18-year-old senior, questions arose about whether he had dated any of his classmates.

The new charges were posted Friday afternoon in the state's online database.

Samarin remains in Dauphin County Prison with a $20,000 bond for six other felonies, including identity theft and tampering with public records.

Samarin enrolled in the Harrisburg School District as a freshman in 2012 and masqueraded as a student for four years, even though he had already graduated from high school, according to court records released Friday.

The records said he came to the United States from Ukraine on a visa, that later expired. He then allegedly created the false identity of Asher Potts, and obtained a delayed birth certificate and Pennsylvania driver's license.

Potts had reportedly been living with a couple named Michael and Stephayne Potts. Court records noted they helped him enroll in school and get his driver's license. It was unclear whether they knew he was older than he claimed.
