C Hing you are so lucky! May be you went down alone so KO did nothing to you ! Once I heard a C Hing who went down with his MM and met KO at the staircase, he was unlucky as KO stopped and questioned them seperately, finally KO escorted them back to the flat and asked them sitting on bed then took some photos as evidence. They were escorted back to KO station to give statement. Eventually the C Hing needed to pay money to settle the case.
