Hi Every body,

Has he(thief) been caught?    OR
 Is he caught?
Which one is correct and why?
if both are correct, what are different usages?
Has he been caught?
Is he caught?

Both are OK. Using 'caught' as an adjective (#2) is casual/informal.
Thanks very much. I didn't expect that you guys will answer so soon. You guys are super fast. I visited this site for first time today. My experience has been great. Thanks again. And I will be back with more questions. Hope, I will find help again.
