There is very little we are able to tell a 3rd party, Jan - but perhaps you could pass on some generic information to your friend.
This is open for an investigation, so that part is already proceeding.
He needs to find out how someone got hold of his password and ID because if that source still exists, they WILL be back.
When an account is used by a 3rd party for malicious behavior, we have no choice but to shut it down unless and until a player has a chance to address the source of the issue. It is every player's responsibility to maintain the security of their system and their account. This is not at all uncommon in a compromise situation, they don't steal these to do 'nice' things with them.
If you could pass on the information below, that would also be most helpful.
