Do the security look in your back pack if your back pack was left there or do it go to lost and found

Yes they will check it and secure

Security and lost and found is the same. Yes, they will.

Security is lost and found there and they go through to see if they can find an ID and if you don't go pick it up they keep your stuff

Yea they will probably

I dont know. But i would look thru your pack. Dont bring drugs and leave you pack behind would be my advise

They will look through it
