Abdirashid Ismail Said, who is the central suspect in the Minnesota fraud scheme case has disappeared, officials said. 

Minnesota Attorney General Keith Ellison has said the case marks the "largest-ever Medicaid fraud prosecution.

Said, 50, did not show up for a pre-trial hearing on Tuesday. 

Ellison on Friday described Said's disappearance as "a deeply frustrating setback."

Local news outlets reported that a warrant has been issued for Said's arrest and a judge ruled that his $150,000 bond must be forfeited.  

Ellison's office has charged Said and two others for alleged involvement in a scheme to defraud Minnesota's Medicaid program. The fraud totals about $11 million.
