Nine arrested, seven juveniles not named, the two adults:
Asha Warfa, 19, of Mendota Heights was booked and released pending charges. And Addirahman Hassan, 21, of San Diego was held on probable cause aiding and abetting robbery charges, and is currently at HCADC.
Based on the names, these are clearly folks of Scandinavian background as are common in this part of the upper Midwest.
Given the extent of Islamic immigration to Scandinavian countries in the past couple decades, you may be right.
