The FBI says it has made an arrest in an Oregon bank robbery after the suspect posted a claim of responsibility on Facebook.

Spokeswoman Beth Anne Steele says Ryan Homsley was arrested Friday. She says investigators filed a complaint Wednesday in federal court, charging Homsley with Tuesday's robbery at a Key Bank branch in suburban Tualatin.

Steele says Homsley has been a hospital patient since Thursday and would be scheduled for a court appearance upon his release.

A posting on Homsley's Facebook page said "im doing this to pay for my medical expenses. ... live for today!" His brother has said Homsley has a serious drug problem and is a diabetic.

He was dubbed the "Where's Waldo" bandit, based on his appearance in surveillance photos.
