Authorities have detained someone whose car apparently ran off the road and onto former President George W. Bush's lawn Wednesday night.
The Secret Service and Dallas police questioned the man but say they do not believe he intended to cause Bush or his wife harm.
Dallas police responded to the scene, but the Secret Service is taking the lead in the investigation.
Investigators said the man had access to the gated Preston Hollow neighborhood Bush lives on. The man was at a friend's house showing off his Mercury Cougar at about 7:45 p.m., investigators said. (Editor's Note: Earlier reports described the car as a Plymoth Barracuda. It was later identified as a Mercury Cougar.)
The man told investigators he ran onto the Bushes' yard when his gas pedal became stuck.
Bush and former first lady Laura Bush live on Daria Drive, which is a public street but is gated and protected by the Secret Service detail assigned to the former president.
Bush spokesman David Sherzer said the Bushes were home at the time of the incident but were never in danger.
