The net is narrowing in the search for the the mob of “clean cut and well dressed” young men and women who attacked and brutally beat a gay couple in Center City last Thursday.

Police this week released surveillance video of a group of people strolling the streets of Center City that they've identified as the suspects in this heinous hate crime. That was followed by the ace sleuthing of one local Twitter user, who was able to locate photos of that same group dining en masse at La Viola West just prior to the attack.

Now G Philly is reporting that the owners of Pennsylvania 6 and its related restaurants City Tap House and Field House are upping the ante. They’ve pledged a $10,000 reward for anyone who comes forward with information leading to the arrest of the attackers.

Philadelphia Police Department released the following information for anyone with tips on the suspects:
