If you did your homework, you already know any Pakistani male is going into extended AP after the interview. No way was the visa going to be approved at interview. This has been true for more than twenty years. If a PCC is not available, it won't be required. You don't mention the country. Even so, the Dept. of State will now begin the extensive, expensive, on the ground investigations every Pakistani Male and many Pakistani females go through after an otherwise successful interview.
Relax. He's in AP. It's expected, not a secret, and should not be a surprise to you.
