Edward Jonathan Krastof, 38, was arrested at his home late on Tuesday in Concord, Calif., the same town where the computer was stolen earlier this month, said Concord Police Sergeant Steve White.

Krastof, who works at Home Depot, confessed to stealing the computer, as well as another computer and a laptop, after breaking into the office of an analyst for Wells Fargo, White said.

Police recovered the equipment at Krastof's home, along with equipment used for scanning identity cards and checks, he said.

"He is a low-level ID theft kind of guy," White said of Krastof.

Krastof told police that he did not know that sensitive data was on the computer, White said.

Wells Fargo will be able to keep the $100,000 reward it had offered in the case, since the arrest was made from regular police work and not a tip, White said.
