Contact with previous owner
Hi.
Several days ago have buy an iPhone SE from second-hand, which is locked by Activation Lock (Find My Phone service or something else). This human is not a original owner of this device, i guess, that it was stolen. How can i know the original owner e-mail to contact him about this device? I can attach device's S/N or IMEI, or some original owner's g-mail symbols, that iPhone shows me at activation step.
Thank You.
