The 75-year-old owner of a Darien day spa pleaded guilty last week to not reporting nearly $145,000 in income from his business.

Nusrat Rizvi, of Norwalk, waived his right to a grand jury indictment and pleaded guilty to filing a false tax return during proceedings before U.S. District Judge Jeffrey K. Meyer.

Rizvi owns Lanphier Day Spa, Inc., on West Avenue in Darien.

U.S. Attorney Deidre Daly said Rizvi admitted that from 2008-10 he took about $144,776 in payments, deposited them in his bank account and failed to report the money to his accountant or the Internal Revenue Service.

As part of his plea-bargained deal, Rizvi will pay $50,485 in back taxes and $37,862 in penalties. He faces up to three years in prison and a $250,000 fine when he is sentenced Jan. 14, 2016.
