bypass iphone activation

I bought a phone for a friend, well a person i thought was a friend. She used the phone for a week without paying for the phone, when i asked her for the funds for the phone she refused to give it to me. she put an apple id and password on the phone. I can't get to unlock the phone. The phone screen is white it just reads activate phone which i cannot do unless i have her apple id etc... I need someone who can bypass the activation screen and allow me to use the phone. i need remove iCloud activation with FIND MY IPHONE removed, so i can activate the iphone and bypass Apple id ans password at first activation of iphone.
