A Mankato man was taken into custody Monday after an incident in which they were attempting to arrest him on a warrant. Blue Earth County court records say 27-year-old Mahad Mohamoud was charged with counterfeiting of currency and giving a peace officer a false name. Authorities say Mohamoud allegedly used a 50 dollar counterfeit bill and gave officers his brother’s name. The court report stated Mohamoud had active warrants for other offenses in Blue Earth County.
