Colyn Tusing, 20, was busted at about 5 p.m. Saturday inside the store in the city of Sandusky.
Cops were called to the location when Tusing refused to leave the store after ignoring a worker’s request to wear a mask, according to an arrest report from the Perkins Township Police Department.
After an officer told Tusing to leave the Walmart, he put on the brass knuckles that were in his pocket as he walked away, the police report said.
Tusing was arrested and the officer removed the weapon from his hand.
The suspect asked the cop: “Do you really think I’m f—ing scared of you?” according to the report.
Tusing was also carrying an orange razor blade knife in his pocket, which police confiscated. He was charged with carrying a concealed weapon.
