Ipad 2 icloud locked help
So its probably been asked 100's of times but hear go's.
Bought an ipad off the car boot (swap meet to you yanks) yesterday cheap no life in it changed it up and its icloud locked so rang the police to see if its stolen as i would be willing to return it to rightful owner and its not reported as stolen rang apple to see if it was reported stolen on thete system and if it was could they help me get it back to owner and no its not stollen on there system.
So apple know its not stolen the police know its not stolen but apple wont lift icloud without previous owners say so.
They even asked me to go see the person i bought it off. My reply yes i will go back to the field and see if hrs still there lmfao.
Can someone point me to the terms and conditions that state the relevant details to icloud lock etc.
Thanks for your time in this probably reparative question
