WASHINGTON — A middle school teacher has been charged with possession of child pornography Thursday after police said they found evidence following a search of his home in Arlington, Virginia.

Robert Keith Rowe, 56, is a teacher at Fairfax County’s Sandburg Middle School, Arlington County police said in a news release. At this time, detectives don’t have “evidence to suggest he has had inappropriate contact with children,” police said.

An investigation into Rowe’s online activities began when an Arlington County detective assigned to the regional Internet Crimes Against Children Task Force received a tip about possible criminal behavior, police said.

With a search warrant, police searched Rowe’s Arlington home Thursday morning and arrested him when evidence was found at the scene that resulted in the charge against him.

Rowe is being held without bond.

Police continue to investigate and ask anyone with information about Rowe’s case to contact Arlington County police.
