A friend of mine picked up a stolen car unbeknownst to my friend, then was caught by police. The person who actually allegedly stole car took off running and wasn't caught on scene as my friend stood there not knowing what was going on and was taken in for interview. My friend made a statement and after further investigation was exonerated and not charged. The person who allegedly stole car was charged under criminal law and is now contesting the charge. So the police needs my friend to now go to court after 2 years as a witness. My question is my friend is studying 1st year Law degree and is worried this may come back to haunt him and be on his national police check. Will going to court as witness for police be on your police check and what are the implications? Will he be OK as he is really stressed out?
