Kirby Dean Guyette, 52, suspected of robbing two banks in recent weeks, was taken into custody Thursday by officers looking for a green van that witnesses described as the getaway vehicle, police Cpl. Jose Gonzalez said Friday.
The alleged getaway driver, 52-year-old Jack Paine, was also arrested, Gonzalez said.
Both men were being held on $50,000 bail. It wasn't clear whether either had been assigned a defense attorney.
Authorities allege Guyette walked into a Washington Mutual branch on Monday and slipped a teller a note demanding money and warning that he was carrying a gun.
That night, teller Nick Wildermuth painted a portrait of the robber from memory. Authorities said the painting depicting a middle-aged man with bushy eyebrows and a salt-and-pepper goatee shared similarities with surveillance video of the robber.
The suspect's unkempt appearance earned him the moniker the "Hobo Bandit."
Guyette, a transient, also matched the description of a man who robbed a Bank of America branch in Santa Ana on Jan. 21, then attempted to rob the same branch several days later, police said.
"The teller recognized him and said, `You're not getting anything from us,'" Gonzalez said. "The suspect appeared confused, turned around, walked out and got in the same green van."
