LAWRENCE, Kan. (AP) — Lawrence is seeking more than $500,000 from the developers of the upscale Oread hotel located 1 ½ blocks from the University of Kansas campus.

The Lawrence Journal-World  reports that a city-ordered audit has found that developers of hotel filed incorrect sales tax returns. The audit says that led to the city and the county overpaying nearly $430,000 in sales tax rebates from January 2010 through May 2015.

The city also is seeking interest and reimbursement for the cost of the audit, bringing the total bill to almost $520,000. City officials are demanding repayment by Dec. 31.

Thomas Fritzel, a Lawrence businessman who leads the development group behind The Oread, didn’t immediately return a phone call from The Associated Press seeking comment.
