A former Honolulu police major already facing extortion, witness tampering, lying to investigators and drug charges pleaded not guilty Friday in U.S. District Court to an additional charge of lying on his taxes.

A federal grand jury returned a new indictment this week against Carlton S. Nishimura, 56, charging him with filing a false individual income tax return for 2005, in addition to the other charges listed in previous indictments.

The FBI said based on an analysis of Nishimura’s bank records, divorce files, tax returns, records of expenditures and transcripts of FBI interviews with him, an Internal Revenue Service agent determined that Nishimura’s cash expenditures in 2005 exceeded what he reported as taxable and non-taxable income by more than $10,000.

Nishimura reported total income of $79,202, the indictment said.
