TPD Chief Chris Magnus said TPD is looking into several downtown establishments in connection to the department's on-going investigation into an increase fights and other criminal behavior occurring in that area.

"Let me clear about this. While we think it is a very small number of businesses that are engaged in this kind of unsafe practices and poor management, there are definitely more than one," he said. "We are not going to let our downtown get a black eye because of persistent bad behavior involving a small, but nonetheless, attention-seeking individuals."

Police said the drug involved in the bust was cocaine.

"Overselling alcohol leads to fights," Magnus said. "This activity gets recorded. It gets posted online. Then all of this encourages the same behavior."
