Police are investigating gunshots heard near the White House on Friday night, according to multiple reports, but the incident appears unrelated to President Obama, who was not in Washington at the time.

An AK-47 assault rifle was recovered from a car near the Roosevelt Bridge shortly after police started pursuing two vehicles fleeing from a section of Constitution Avenue near 16th street, where the shots were heard.

Secret Service spokesman Ed Donovan said it did not appear the incident was focused on the White House, and that the U.S. Park Police was taking the lead on the investigation.

Witnesses saw the driver of the vehicle where the gun was found run across the bridge toward Virginia, according to the AP.
