WASHINGTON — Police in Virginia say they’ve arrested a knife-wielding man found wandering in a field near an elementary school Thursday.

The incident happened near Oakton Elementary School at around 12:30 p.m. Teachers notified police about a man they spotted near school grounds with a knife.

When Fairfax County police arrived, officers discovered a blue station wagon parked behind the school. The vehicle was running, but no one was inside, police said. William James Przystup, 32, of Oakton, was later found laying in a tall grassy field behind the school.

Police allege that Przystup had a knife.

Przystup was charged with possession of a weapon on school property. He was taken to the Adult Detention Center and is being held without bail.
