WASHINGTON — A person with a weapon was arrested Wednesday at a building that houses several foreign consular offices in Northwest Washington, Secret Service officials said.

About 10:45 a.m. Wednesday, Secret Service officials responded to reports of gunfire in a neighborhood that hosts restaurants, hotels, apartments and some diplomatic offices. Law enforcement officers determined that no shots had been fired, but they arrested and charged an armed person with assault, officials said.

Metropolitan Police in Washington are now handling the arrest, and Secret Service officials declined to comment further on the incident, citing an ongoing investigation.
