CONCORD, NH — Greek-American Thomas Katsiantonis, 44, a New Hampshire State Representative and Manchester Ward 8 alderman, was arrested Thursday on four counts of tax evasion and theft charges involving $423,000 in state meals and rentals tax payments, the state Attorney General’s Office announced.

State Attorney General Gordon J. MacDonald and Department of Revenue Administration Commissioner John T. Beardmore, in a joint news release, said Thursday that Katsiantonis is charged with four counts of tax evasion, two counts of theft, one count of falsifying physical evidence and one count of unsworn falsification, Union Leader reported.

Manchester Mayor Ted Gatsas called on Katsiantonis to resign shortly after the charges were announced.

As TNH has reported in mid-February, Federal and state investigators searched the home and two businesses of Ward 8 Alderman and representative Thomas Katsiantonis along with another city business following a months-long criminal financial investigation.

Investigators searched the alderman’s home and his businesses, Grand Slam Pizza 2, 331 South Mammoth Road, and Tommy K’s Sport Bar & Restaurant, 2323 Brown Ave.

Katsiantonis and his Grand Slam Pizza business owe more than $427,000 to the state Department of Revenue Administration and face state tax liens, according to the Union Leader. That total includes more than $324,000 in “meals & rentals tax” dating back to 2012, as well as penalties, fees and interest accrued, according to court documents.

Thomas Katsiantonis is a Democratic member of the New Hampshire House of Representatives, representing Hillsborough 15. He was first elected to the chamber in 2008. Katsiantonis served in the House previously, representing Hillsborough 15 from 2003 to 2004. Katsiantonis was a candidate for Hillsborough 15 in 2006, Hillsborough 17 in 2004, and Hillsborough 50 in 2002.
