After responding to a job ad posted to Craigslist, a woman showed up to an unassuming office park in Reston. Instead of interviewing for a position as an administrative assistant, she was sexually assaulted by a registered sex offender, according to Fairfax County Police.

Imtiaz Rauf, of Gainesville, Virginia, has been charged with sexual battery. Police say they have received other similar reports and “additional charges may be forthcoming.”

Rauf was convicted in 2011 of sexual solicitation of a minor in Montgomery County and placed on a sex offender list. He is being held without bond.
