Bin Laden hunter Gary Faulkner back home in the US

Denver: Gary Faulkner is back home in Colorado after his personal quest to track down Al Qaida leader Osama Bin Laden ended with his arrest in northern Pakistan.

The Greeley, Colo., man was detained June 13 when authorities found him armed with a pistol, a sword and night-vision equipment.

He was released Wednesday morning in Pakistan and reached Denver around midnight.

The tired yet buoyant construction worker spoke briefly with reporters, saying he was feeling good. "All I want to do is get some rest."

Faulkner declined to answer questions about his trip or his immediate plans as he was hustled through the airport by his brothers, Todd and Scott.

But during a stopover in Los Angeles, Faulkner was asked by reporters if he planned to return. "Absolutely," he said. He added cryptically, "You'll find out at the end of August."

Faulkner said he was well cared for during his confinement and that Pakistani medical workers administered dialysis to treat his kidney disease.

Scott Faulkner, a physician in the northeastern Colorado town of Fort Morgan, said he intended to check Gary's health on Thursday.

In Pakistan, Gary Faulkner told officials he was out to kill the Al Qaida leader. He was eventually moved to Islamabad before being released without charges, according to Scott Faulkner.

He also spoke about his intent to get bin Laden.

He said organising his trip "took a lot of money and a lot of time."

"This is not about me. What this is about is the American people and the world," he said in comments aired on KTLA-TV. "We can't let people like this scare us. We don't get scared by people like this, we scare them and that's what this is about. We're going to take care of business."
