The Freeport Warehouse was the target of a heist by Leonard Snart.
Leonard Snart's first ever job he worked with Mick Rory on was a heist of the Freeport Warehouse. Leonard planned the hit on the warehouse for three weeks, casing out the warehouse and memorizing the staff's shift changes and delivery schedules. However, during the heist, they discovered the owners had upgraded the warehouse's security system forcing Leonard and Mick to abort the plan.
Leonard would later keep a ring from the Freeport Warehouse job to always remind him that the best plans can always go wrong.
