The weekend after police had to use pepper spray to quell several fights among a hostile crowd in the troubled 600 block of University Avenue, officers were out in force driving home the message that violence and intimidation by people congregating outside Downtown bars won?t be tolerated. At 12:30 a.m. Saturday, three marked police vehicles were parked on the north side of the 600 block of University Avenue with several officers standing watch on the street as two others handcuffed a man suspected of dealing drugs. A fourth squad car was stationed across North Frances Street from Wando?s bar, where the mayhem had broken out early July 22.
