Your friend probably used some blackhat SEO techniques Begin by asking him what he has done, then try to correct it, and then file a reconsideration request at Google here: https://www.google.com/webmasters/tools/reconsideration
I now you cannot reveal it, and please be careful next time. there are many reason for that like - blavkhat link building, copy-pasting content from other and so on. Please read the terms and conditions of google carefully. I am really sorry for that mishap.
