White House on brief lockdown after man on grounds said he had bomb

March 28 (UPI) -- The White House went on lockdown for 45 minutes Tuesday morning after a man told authorities he had a bomb near the grounds.

The U.S. Secret Service announced at 10:42 a.m. on Twitter: "SecretService investigating suspicious package near @WhiteHouse grounds. Road closures in effect."

Then, 16 minutes later, it posted: "security perimeter established & members of the public & media are being moved to safe a distance."

The lockdown was lifted at 11:50 a.m. and the Secret Service said one person was taken into custody.

An agency spokesperson told reporters a man holding a package approached a uniformed officer at 15th Street and Pennsylvania Avenue at 10:15 a.m.

An unidentified source told Fox News the man said he was carrying a bomb in his bag.

Journalists in the press room were told to stay in place and media were ordered off the North Lawn.

East Wing tours also were suspended.

Ten days ago, a person jumped over a pedestrian barrier outside the White House. Later that day, a man was arrested after driving his car up to a Secret Service checkpoint at 15th and E Street Northwest.

On March 10, a 26-year-old California man cleared the White House fence and was on the grounds for about 17 minutes.
