Is this true about the capture and imprisonment of Nelson Mandela?

I just saw a status update on my facebook that said, ”...the reason Nelson Mandela was captured and spent 27 years in jail, was because our CIA told the racist South African government where to find him. Yet another sad chapter in American history.”

Is that true? I know I can google the history, but I’d like to hear what the collective has to say about it. Please feel free to expand on the events leading up to his capture.

Thanks.
