KNOXVILLE, Tenn. (WVLT) -- It's becoming a familiar site in Knox County. Another city business boarded up and shut down by cops as a so called nuisance.

"We don't like it. It affects a lot of our clients. We're just happy to see it shut down for now," says Ron Richardson, who works next door to the bar.

Says John Gill with the Knox County DA's Office, "we're certainly going to focus where there is ongoing and open criminal activity."

Prosecutors say Mickey T's owner Michael Penrod was already facing drug charges in a separate case when police busted him again during the raid. "There was ongoing drug sales, particularly prescription drug sales and, in fact, the owner is under indictment for criminal drug sales," says Gill. Cops locked up three others in connection with drug sales inside the bar.

Says Gill, "we hope this has a deterrent impact and I think it will."

But he believes this won't be the last business police shut down for being a criminal haven. Richardson agrees. "I hope it stays shut down."

"We've got some locations that have been problem areas that we're going to take a look at," says Gill.
