WASHINGTON, DC — The all-clear has been given after an active shooter scare in downtown D.C. just blocks from the White House on Tuesday turned out to be a "domestic" incident with no shooting, police say.

Police cordoned off 17th Street NW between L and K streets due to a possible active shooter, and people on social media reported a huge police presence in the area.

At around noon, a Twitter user posted photos that appeared to show police taking a man into custody.

D.C. Police tweeted at 12:05 p.m. that they were investigating a "domestic-related incident" at the intersection of Connecticut Avenue and L Street NW, and that there was never an active shooter. They added that they had one suspect in custody.

D.C. Police tweeted at 12:43 p.m. that all streets that had been closed to vehicular and pedestrian traffic had been reopened.

Residents of cities across the United States have been on edge after recent mass shootings in El Paso, Texas and Dayton, Ohio. Last week, a motorcycle backfiring caused a mass panic in Times Square, with a stampede of people fleeing the area thinking the sound was gunshots.

EarthCam, a company that hosts live streams from various locations across the globe, released footage of the stampede from three different angles. A packed Times Square empties out in minutes as an initial wave of people running from the scene inspires others to follow in confusion.

Mayor Bill de Blasio assured New Yorkers that the Midtown Manhattan hotspot was safe around 11 p.m., but added that recent mass shootings have left people on edge. Thirty-one people were killed during shootings in El Paso, Texas and Dayton, Ohio in recent shootings.
