Not long afterwards, the Secret Service said it was a person who had shot themselves.
President Donald Trump is at Mar-a-Lago for the weekend with the First Lady Melania Trump and their son Barron.
DC police say there is not thought to be any outstanding threat. Some streets around the White House were cordoned off and officers armed with rifles patrolled the area.
Media which were in place there tweeted that they were being told to shelter until further notice, according to the Daily Mail.
NBC's White House correspondent Geoff Bennett tweeted first about the incident
"We're sheltering in place at the White House briefing room. A report of 'shots fired' near North Lawn, per a U.S. Secret Service agent.
"Trying to learn more," he said.
Tourists who were in the area shared reports of hearing 'shots fired'. They were unaware if there was any threat to them or anyone else.
Within minutes of the shooting, the Secret Service calmed panic.
"Secret Service personnel are responding to reports of a person who allegedly suffered a self-inflicted gunshot wound along the north fence line of White House.
"No other reported injuries related to the incident," it tweeted.
President Trump is aware of the shooting, according to White House officials.
He spent the morning golfing in Mar-a-Lago and had not long returned to his residence there when news of the shooting emerged.
