The gun rights group Wisconsin Carry filed a federal lawsuit Wednesday against the city of Madison and Police Chief Noble Wray claiming the constitutional rights of the group and its members were violated when police demanded that five members who were openly carrying handguns while eating at a Culver’s restaurant produce identification or face arrest.

The suit filed in U.S. District Court in Madison also alleges the rights of the group and its members were further violated by a new policy the department established after the Sept. 18 incident, claiming the policy was designed to prevent the right to bear arms and subjects people to unreasonable searches and seizures.

It asks for a court order prohibiting the department’s alleged practices, along with attorneys fees and unspecified damages.

Wray has acknowledged police erred in issuing obstructing citations to two of the five men, who refused to identify themselves to officers sent to the Culver’s near East Towne Mall after a 62-year-old woman called 911. The obstructing citations were rescinded, but all five men were later cited for disorderly conduct.
