How to get back into the Confiscated Goods vault

batman-arkham-city

I've been attempting to complete riddler challenges, and noticed that there are at least two collectibles inside TYGER's confiscated goods vault that I missed (map below). I've looked for a way in, but found the main door locked and the tunnel Catwoman used to enter entirely blocked off by Poison Ivy's plants. How the heck do I get back in there?
