The shooting happened just after 9 a.m. Wednesday at the post office on North Church Street in downtown Lovettsville, a small town of about 2,000 people in northern Loudoun County.
The postal employee who was shot was taken to the hospital with injuries that were not believed to be life-threatening, according to the Loudoun County’s Sheriff’s Office.
The special agent who fired his weapon works for the U.S. Postal Service Office of the Inspector General, according to Agapi Doulaveris, an office spokeswoman. She said the officer was involved in “a critical incident … which resulted in the agent discharging his firearm and shooting a Postal Service employee.”
