From the Eureka Police Department:

On 3-20-12, the Eureka Police Department’s POP unit, while conducting drug investigations at the 2200 block of Broadway, arrested William Joseph Farrell. William Joseph Farrell is the suspect in the February 2nd robbery of the Bayshore Mall’s Coast Central Credit Union. The arrest was made without incident and Farrell was booked into the Humboldt County Jail.

It appears Farrell had been back in the area for several weeks.

Farrell is also the suspect in a March 3rd bank robbery in Rockford Illinois. The Chicago based FBI indicted Farrell earlier this week. The federal warrant is expected to be issued on 3-21-12.
