Found an iPad mini in a park in London but it's locked so I reset it and now it's worse than before.

So I have a big problem, I found an iPad mini in a park in London, England. I thought I give it a go and charge to hopefully find the owner of the dam thing but to my luck and probably anyone else that finds these devices now a days, it's code protected. So I figure I give it a full charge and carry it with me on my daily journeys and hope I can find an open wi-fi signal that it will connect to but nothing. It's been almost a month I believe and I'm getting tired of carrying this thing around hoping for some kind of miracle. Well in the long run, I do some Google research to see if there is a way to break the lock code and so I give in to the factory reset because that way I can add the wifi I have at my place of stay. Not before I can finish with the updating it's asking me for the owner's Apple ID and password.

*** Apple. 😐 Now not only can I not get into the bloody iPad but I can't even get the person's full e-mail because it just said's "linked to an Apple ID (h•••••@hotmail.com) blah blah blah"

Now, because of the dam lock screen in the first place, not allowing me to connect to Wi-fi so I could get some info on the owner, now I can't/don't even know what to do considering I reset it to factory settings to see if just connecting it to wifi would pop out a message on the "find my iPad" mode - instead I get a more complicated screen message. Well the damage is done.

Does any one know if now that I have it connect it to Wi-fi, but in factory setting mode, can the owner track it and maybe they can locate it? Or should I just go to my nearest police station and watch them auction it off to the highest bidder? It's not like I can write them an e-mail or plaster a message so they know I've tried everything to find the original owner. I even check to see if they have the iPad register but I the register number isn't popping up anywhere or I'm not looking hard enough.

Any help would be appreciated
