A Fairfax County children's entertainer - who goes by the stage name "Mr. Knick Knack" - is under arrest after detectives allegedly found multiple child pornography files in his possession.

Steven Rossi, 58, of Reston is charged with 10 counts of felony possession of child pornography.

Police began investigating Rossi on April 18 after the Fairfax County police department received a tip.

They say a thorough investigation led to the discovery of the files.

Rossi was arrested on April 30, and posted bail on May 2.

He is scheduled to appear in court on June 11.

"Mr. Knick Knack" has performed at a number of locations throughout Northern Virginia.


Police do not believe Rossi had any contact with any of the children who are in the images, but anyone who believes their child has had contact with Rossi, they should call police at (703) 246-7800.
