A witness who testified against a man accused of operating a multimillion-dollar real-estate fraud told a federal judge the man also ripped off Miami Heat basketball players.

The testimony came Thursday in federal court in Columbus where U.S. District Judge Edmund A. Sargus denied bond to Haider Zafar. The judge determined Zafar is a flight risk and a danger to the community.

"The longer the potential sentence the greater the risk of flight" the judge said according to The Columbus Dispatch.

Zafar who used to live in Ohio but now lives in southern Florida is awaiting trial on wire fraud and other charges. His 135-count indictment describes a scheme it says he used to swindle Washington D.C. businessman Patwinder Sidhu out of $10 million between 2008 and 2010.

Zafar pleaded not guilty last month to all charges. His attorney Samuel Shamansky on Friday said they will continue to challenge the accusations.

A criminal complaint says Zafar a Pakistan native and U.S. legal resident used questionable documents to solicit the funds from Sidhu for real-estate ventures in Pakistan.

The complaint accuses Zafar of telling Sidhu that his uncle was Pakistan's defense minister and was responsible for buying property for that country's government. It says Zafar told Sidhu they could buy land in Pakistan and later sell it to the government for a profit.

The basketball players aren't mentioned in the criminal complaint.
