Former Canyon County Prosecutor John Bujak was in the Ada County Jail Wednesday night after he was booked for a felony charge of evidence tampering.

Idaho State Police made the arrest, which came after Bujak’s first court appearance on a grand theft charge involving an estate he handled before taking office as prosecutor in 2009. Last month, a Canyon County grand jury indicted him on a theft charge alleging he “exercised unauthorized control over multiple checks” for more than $1,000.

In a separate investigation, Idaho State Bar officials say there is evidence Bujak wrongfully took $3,700 in payments intended for the estate in 2008 rather than passing the money on to the client’s new attorney, who later filed a grievance with the bar association.

The association’s professional conduct board filed a complaint in October against Bujak concerning Littleton and another case he handled before he became county prosecutor. In December, Bujak and the association reached an agreement to suspend his law license pending resolution of the criminal and bar association investigations.

Bujak resigned as county prosecutor in September 2010 amid allegations he failed to pay the county several hundred thousand dollars in proceeds from a $600,000 annual contract to use county resources to prosecute Nampa misdemeanors. After an ISP investigation, Bujak was charged with felony misuse of public funds. That case is pending in 3rd District Court.
