Two weeks ago Philadelphia Parking Authority sent notices to approximately 100 taxi drivers, claiming that the drivers were owed money from past credit card transactions and should report to the PPA office on Wednesday, June 30th to receive their unclaimed check. As the drivers arrived at the Parking Authority, they were hand cuffed and arrested. In total, 27 drivers were arrested, 22 drivers were ultimately released and the whereabouts and identities of the other drivers is not known.
