Thomas Bellstrom says he was walking home late Saturday night on Main Street with a group of people. Right next to them, a small gathering paying respect to fallen officer Andrew Widman at the site where he was killed. That's when he says his brother picked something up off the ground.

"He did not know but there was a stray doll on the side of the road, he picked them up and a mob attacked him," said Bellstrom.

He says he thought his little brother was in trouble, so he stepped in to try to break it up.

"All I did was step in and separate the two. Next thing I know I was on the ground, up against the car, in cuffs," said Bellstrom.

Police arrested him and Maxwell Horth. The report says the group was asked to step away from the memorial, but started causing trouble. Other witnesses called it chaotic and confusing.

Police won't talk about what happened because Bellstrom filed a formal complaint. He says it was excessive force, and he wants answers.

"They said I stepped on it,  I did not see it. Nobody saw it. It was pitch black out here," he said.
