DALLAS (AP) - Police say the Secret Service questioned a homeless man who was knocking on doors near the Dallas home of George W. Bush in search of the former president.

Dallas police said Friday the man was picked up last Saturday several streets from Bush's home in the upscale neighborhood of Preston Hollow.

Police spokesman Kevin Janse says police detained the man until a Secret Service agent determined he was not a threat. Police then gave him a ride to a Dallas homeless shelter.

Secret Service spokesman Malcolm Wiley says the man never reached Bush's home. The street is protected by a security gate monitored by federal agents.

The Bushes moved into the home a month after the president left office in January 2009.
