A 29 years old Virginia man arrested outside the White House on late Saturday claims that he was testing the Secret Service with a fake bomb threat, according to the report.

Sean Patrick Keoughan, of Roanoke, drove a reportedly stolen car up to a security checkpoint at around 11 p.m. and told the Secret Service agents that he had “a bomb in the trunk,” NBC News reported, citing the Metropolitan police.

Keoughan said “this is a test,” as the agents tackled him to the ground.

After an hours of long search with a bomb robot, the authorities found no trace of explosives inside the 2017 Chevrolet Impala. The vehicle was reported stolen and had the Indiana registration, according to NBC.Keoughan faces charges of false bomb threats and also unauthorized use of a vehicle. A Secret Service statement issued on Saturday made no mention of explosives but said that an agent deemed the vehicle “suspicious.”

The security alert unfolded as the President Donald Trump spent the weekend in Florida at his Mar-a-Lago estate. President Donald Trump returned to the White House on Sunday night.

It is the third foiled attempt to access the White House in the past three weeks. On Saturday, a man tried to scale the bike rack with a letter for the Trump administration. On March 10th, Jonathan Tran, aged 26, was arrested after successfully jumping the fence and also spending at least 17 minutes on the White House grounds.
