An alert parent at Taylor Elementary School (2600 N. Stuart Street) called police on Monday upon spotting a half naked man near the school.

A mother saw the man sitting in a van near the school’s bus stop on N. 31st Street around 8:20 yesterday morning. When she noticed that he was naked from the waist down, she called police.

The person is described as a white male with dark hair, in his mid to late 40s. At the time of the incident he was in a white Chevrolet Astro van that had ladders on the roof.

Arlington County Police spokesman Dustin Sternbeck said the mother did exactly what she should have in this type of incident.

“If something doesn’t feel right, it’s better to alert police and let them investigate,” Sternbeck said. “The ACPD is following up on the incident and will have an increased presence in the area.”

If found, the man could be charged with indecent exposure.

Next week, nearly 3,400 relay runners will weave through portions of Arlington as part of their nearly 200 mile trek.

Ragnar Relay Washington DC takes place Friday, September 21 and Saturday, September 22, starting at Rocky Gap State Park in Maryland and ending at National Harbor in Maryland. Runners are expected to make their way into Arlington on Saturday morning.

After entering Arlington via Chain Bridge Road, runners will encounter a baton exchange point at Taylor Elementary School (2600 N. Stuart Street). They’ll continue along the Custis Trail until they reach the Key Bridge Marriott (1401 Lee Highway), which is another exchange point. The race continues south on the Mount Vernon Trail past Reagan National Airport, and then participants exit into Crystal City. The final baton exchange point in Arlington will be set up at the Crystal City Water Park on Crystal Drive. After that, the race heads back to the Mount Vernon Trail and south into Alexandria. The full course map and information about each leg of the race can be viewed online. The Arlington legs are 31-34.

Race organizers ask local residents to be extra cautious of the runners on the side of the road, especially because the relay requires them to race at all hours of the day, including at night. Those who are running in the dark will be wearing reflective clothing and headlamps.

Police say they will not be closing roads due to how long the race is and how spread out the runners are by the time they get to Arlington.
