Prosecutors want a Ramsey County judge to keep 10 people they identify as members of two rival gangs out of the Minnesota State Fairgrounds and the surrounding blocks for all 12 days of this year’s fair, citing brawls at the last two fairs and Instagram posts they say advertise a fight on the fair’s third day.

Ramsey County Attorney John Choi and Minnesota Attorney General Keith Ellison filed a pair of civil complaints Wednesday evening, one against a group called Muddy and one against a group called The Ville, asking the court to declare each a criminal gang and a public nuisance under Minnesota’s civil gang injunction law. Each filing came with a motion for a temporary injunction, a memorandum of law and sworn declarations from law enforcement.

The requested restrictions would run from 8 a.m. Aug. 27, opening day, to 6 a.m. Sept. 8, the morning after the fair closes on Labor Day.

Minnesota State Fair Police Chief Ron Knafla, who also holds the rank of commander with the Ramsey County Sheriff’s Office, laid out the proposed boundaries in a declaration filed in both cases. The “Safety Zone” would cover the entire 322-acre fairgrounds plus a buffer running out to Cleveland Avenue North and Hamline Avenue North, about three blocks north of Larpenteur Avenue West and about three blocks south of Energy Park Drive.

Inside that zone, the named members couldn’t associate with one another or with other known members of their gang anywhere in public view or open to the public. That covers standing, sitting, walking, driving, bicycling or gathering together. The filings carve out one exception. The restriction wouldn’t apply inside a church.

The proposed order would also bar them from confronting, intimidating, harassing, threatening, provoking, assaulting or battering anyone known to be a witness to, a victim of, or a complainant about the gang’s activities.
