Adrienne Fragatos said she was just trying to get help for her mom, who had collapsed, when she was arrested at a concert. Adrienne was attending an Imagine Dragons show with mom Karen. The pair stood for three hours listening to the pop rock band. When it came time to leave, Karen became ill. "As we started to walk, my mom collapsed. Her legs gave out. I was petrified," Adrienne said. So the frightened daughter called 911.
