U.S. Bank Stadium and the Viking ship sculpture outside of it were among the structures targeted by vandals on Saturday evening.
Minneapolis police say a group of 50-100 people congregated in south Minneapolis around 10 p.m. and headed towards downtown before they "dispersed on their own" at Elliot Park.
A police report over notes that "damage was done along the way" and it appears that much of it centered around U.S. Bank Stadium.
Anti-police graffiti was sprayed onto several buildings and structures, including the Viking ship at the north entrance to the stadium, the U.S. Bank Stadium sign, and nearby buildings belonging to Hennepin County.
Minneapolis Police Department told the Star Tribune that it is checking video surveillance to try and identify those responsible for the graffiti.
The stadium itself was not damaged, with the newspaper noting the vandalized areas are fenced off for repairs.
