Happy Askar, the owner of the popular pizza chain, Happy’s Pizza and four others, who work for him, were indicted by a grand jury with tax fraud and obstruction, along with other charges in U.S. District Court on Tuesday. 

The names of the other four are Maher Bashi, Tom Yaldo, Arkan Summa and Tagrid Summa Bashi.  Bashi and Yaldo are accused of underreporting payroll expenses, paying employees in cash and failing to report income to the IRS, according to a report. 

Summa and Summa Bashi are also named as defendants. Summa is charged with obstruction for concealing his role in the company, and Summa Bashi is charged with providing false information to IRS special agents. 

Three years ago, federal agents raided the Happy’s Pizza headquarters in Farmington Hills.  

The pizza chain started out with one store on 7 Mile in Detroit and has expanded into other states such as Indiana, Ohio and Illinois. The company says that it is fully cooperating with the investigation.
