The United States Secret Service arrested a man who officers believe fired a gun near the Ethiopian Embassy in Washington, D.C., according to Reuters.

U.S. Secret Service spokesman Brian Leary said in an emailed statement that when Secret Service officers investigated a report of shots fired around 12:15 p.m. Monday, they detained a man believed to be the shooter, Reuters reported.

His name was not released and the Secret Service says there were no reported injuries, according to Reuters.

The person believed to have fired the shots turned himself in to authorities, and no arrests were made because he has diplomatic immunity, Reuters reported.

Witnesses said the gunfire took place inside the embassy compound during a protest against the Horn of Africa nation's government, Reuters reported.

"About half a block from the embassy, I heard at least four shots, and I thought there were people killed," demonstrator Tesfa Simagne told Reuters Television, according to Reuters.

A video taken inside the embassy gates and carried by the website of Ethiopian Satellite Television shows a man wearing a dark suit and brandishing a silver handgun, Reuters reported.

In the video, he points the weapon at others who argue with him and fires a single shot, then, still waving the gun and arguing with protesters, the man backs up to an embassy door and goes inside, according to Reuters.

A separate video made by a protester and provided to Reuters showed a bullet hole in the windshield of a car protesters said was outside the embassy gates, Reuters reported.
