At least seven people were arrested and dozens hospitalized during country singer Kenny Chesney's concert in Pittsburgh on Saturday, authorities said.
McLay said the number of arrests was low given the "incredible amount of alcohol being consumed by people, a lot of whom seem to have a hard time controlling it."
There were also summons arrests, and about seven citations issued, McLay said. "For the number of people and the amount of alcohol, those are low numbers. Largely, they’re low because officers did everything they could to maintain order without having to make arrests," he said.
