[xwiki-users] Delete document by ID with velocity or direct from database ?

Hi. Is there a way to delete (e.g. using Velocity) document by it's ID ? One of my documents received bad name (I suppose lack of some input validation in rename form), I tried to fix it in xwikidoc table, and now I cannot access it in any way. I don't need it, but how to remove it safely? TIA, Ryszard.
