<human>: So I live in a residence at university. Each floor is only accessible by key by people who live in that wing of the building. Ie people above and below me have access to my floor.

All students are on a meal plan. I like to cook and in each common room there is a common fridge and freezer. So i store my food in the fridge and leave my pots and pans in the common room because i am generous and like to make things available to others. I would store the food in my room but i dont have room in my mini fridge as i keep my booze there. Booze wouldnt last a minute in the common room. I also keep my really expensive meats in my mini fridge. 

So A few months ago my frying pan was stolen along with some raw sausage. I found the sausage in another freezer on another floor but never found the frying pan. After putting up signs and waiting a few weeks it was returned. Since getting back from winter break it seems we cant leave anything in our fridge other than raw vegetables because after 1 or two nights it will be stolen. We have seen a stranger from another floor periodically perusing our fridge and when people have caught him in the act theyve been too scared to do anything or didnt realize what he was doing. Its mostly me and two friends who have had our stuff stolen. 

So he mostly comes down around 2-4am as that is when the instances have happened (yes im up at 4am sometimes checking). My friend and i both have lots of work and thus cant stand guard. Any ideas of how to catch this guy? My only idea is to scare him by putting something enticing in the fridge and when he looks inside itll say "we've got you on camera this time".

Anyways i just talked to my resident advisor and hes bringing it up in his meeting with the other RA's to see if they know anyone by the description we have of this guy. Its late im sleeping. peace /end rant

Condense the text into a few key points
