WASHINGTON — Fairfax County police have arrested a Northern Virginia dance instructor accused of having a sexual relationship with a 14-year-old student and inappropriately communicating with other teen girls.

Chase Clark Peklo, 19, of Sterling, Virginia, was arrested Thursday on warrants of carnal knowledge of a child between 13 and 15 years old and five child pornography counts, Fairfax County police said Friday.
