Arkham City Incident
Strange's Confiscated Goods Vault was a vault that contained confiscated goods. Catwoman wanted to steal two briefcases, and with Poison Ivy's help, she broke in. But instead from escaping Arkham City with her loot, she choose to save Batman, who was fighting Joker's Henchmen, and after a collapse of the ceiling in the Funhouse at the Steel Mill, became stuck in the rubble.
