Arlington County police are searching for a man they say exposed himself to a 14-year-old boy.
It happened around 10 a.m. Tuesday in the parking lot at Washington Lee High School.
Police say the suspect was wearing nothing but white, athletic socks and white, Nike shoes when he jumped in front of the teen.
Luckily, the victim got away and called police.
But, this is just the latest case in what appears to be a rash of similar crimes.
Arlington resident John Skaggs said, "Very disturbing. We're on school grounds here in Arlington and just the thought of a gentleman coming up to young adults in that manner is just completely disgusting and very upsetting."
Police say the suspect, dressed only in his socks and shoes, was crouched down in a secluded area of a second level parking deck.
When the 14-year-old student walked by, the man surprised him - naked. Police say the teen took off and call 911.
Susan Daniero, who lives across from the school, said, "It's just shocking that would be in north Arlington."
"It can be frightening anywhere, whether it's school property, whether it's on any street, whether it's day time or night time," Arlington County police spokesman Dustin Sternbeck added.
Police in the county are investigating more than a dozen indecent exposure cases since March. A quarter of those incidents happened in June alone.
Sternbeck said, " In each of those cases, it varied from whether it was hours to days of when the victims actually reported the crime."
On June 1, a woman sitting in the outdoor patio area of a restaurant on Wilson Boulevard in Clarendon discovered a man around 60-year-sold staring at her and flashing himself under a table.
A few weeks before that a different man was spotted masturbating in public as he watched children on a restaurant patio on North Fillmore Street.
Police describe the suspect in the Washington Lee high incident as a white male, 6'2? tall with an average build and short dark hair. He was wearing wired glasses at the time of the incident. Anybody with information about the incident is asked to call Arlington police at 703-558-2222.
Police don't believe the other flashing cases are related.
