WASHINGTON, May 6 -- The White House was locked down temporarily Tuesday afternoon after a vehicle followed a motorcade into a secure area, according to local media reports.

A U.S. Secret Service spokesperson said a vehicle followed a motorcade into the secure area Tuesday afternoon and put the White House complex on lockdown, CNN reported.

The driver of the vehicle was stopped by Secret Service uniformed officers at a checkpoint and taken into custody and police checked the car for explosives.

The motorcade included the two daughters of U.S. President Barack Obama, CNN quoted a source familiar with the incident.

In about an hour, the security lockdown was lifted.
