A Secret Service special agent protecting U.S. Treasury Secretary Janet Yellen opened fire early Tuesday on people who were suspected of car break-ins. Yellen was not harmed and there’s no indication she or the Secret Service were specifically targeted. Per Politico, it was unclear if Yellen was home at the time of the incident.

The Secret Service said in a statement that a special agent was working “a protective assignment” on Stephenson Place NW in Washington, D.C., at about 1:30 a.m. when the agent “observed a sedan with multiple occupants who were attempting to open car doors along the street.” The occupants of the vehicle confronted the Secret Service agent, and fled the scene after an agent fired shots, authorities say, adding that there was no evidence anyone was shot.  The Secret Service said that “there was no threat to any protectees during this incident and no protectees were harmed,” and the search for the suspects is ongoing.

An investigation by the Metropolitan Police Department’s Force Investigations Team is underway, with the case also under review by the U.S. Attorney’s Office.
