WASHINGTON (DC News Now) — U.S. Secret Service police cleared people out of Lafayette Square Friday afternoon for what was described as a “public safety issue.”

The closure of the park, which is located across from the White House, did not last long. People were allowed to reenter by 4:40 p.m.

Although officers with United States Park Police were there, the agency referred all questions about the situation to the Secret Service.

At 5:35 p.m., the Secret Service updated DC News Now and said that the reason police cleared the park was because someone there had a mental health issue, and, out of precaution, officers evacuated the area until the situation could be addressed and help could be gotten for the person.
