As previously reported, an angry Somali woman 'working' at a daycare – with no children inside – slammed the door as journalist Nick Shirley asked some simple questions about the so-called children's center.

Minnesota Childcare Center claims it takes care of 102 children, however, the facility is empty.

"We're just wondering where the children are," David, a man who has been investigating the Somali fraud for years, asked. "It says you have 102 children here, and you got $2.66 million this year in funding. And $2.5 million last year. We're just wondering where the kids are."

"And who are you?" the Somali asked.

"My name is Nick Shirley," Shirley said.

"And which department?" the Somali asked.

"We'd like to ask where the money is going," Nick Shirley said as the Somali slammed the door on him.

This is just the tip of the iceberg.

Somali healthcare scammers may have stolen more than $9 billion in taxpayer money in Minnesota.

Federal agents descended on Somali businesses in Minneapolis on Monday.

"Homeland Security Investigations @ICEGov are on the ground in Minneapolis right now conducting a massive investigation on childcare and other rampant fraud," DHS Chief Kristi Noem said.

"More coming," Noem added.

"DHS is on the ground in Minneapolis, going DOOR TO DOOR at suspected fraud sites," Homeland Security said.

"The American people deserve answers on how their taxpayer money is being used and ARRESTS when abuse is found. Under the leadership of @Sec_Noem, DHS is working to deliver results.
