The owner of the computer, or someone in control of the owner's Apple ID, has remotely locked it. It is a facility by Apple to lock the Apple devices remotely if it is lost or stolen. In your case, contact the real owner to unlock it. If that person is not available, make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have it unlocked. You may be asked for proof of ownership.

Note: Another option we can try in this situation is boot from the installation disk and install OSX after fully erasing the hard disk, but if the
system has been locked by iCloud it has actually put a firmware password ***** your system and it will not allow you to boot from an external media. .

I understand that this answer may not be entirely to your liking, and I regret being the bearer of information that you really don’t want to hear. But it would be unfair to you and unprofessional of me where I to provide you with anything less than truthful and honest information.
