Groups of looters hit two Best Buy stores in Minnesota’s Twin Cities just after 8:00 p.m. on Black Friday, according to reports.

One of the looting frenzies occurred at the Burnsville Best Buy, where 20-30 suspects rushed the store in a flash mob-style robbery, KSTP reported.

Burnsville Police Capt. Don Stenger said that no weapons were used in the Burnsville shoplifting incident, according to the Star Tribune. “We don’t know exactly what was taken or the dollar value,” Stenger added.
