Tolu Marina Tours

Was accused of smoking in the room which I was not, I was in the shower. Security said someone complained of smoke, then he said you can smell in the lobby from the 7th floor and then he said the smoke detector went off silently in the room with the sprinkler system not engaged. No visible smoke in the room and they stayed over 5 mins while I stood there naked in a towel saying it smell like smoke. I showed them the bathroom where I just got out of the shower bc they were knocking and made me late for dinner. I didn't smell anything at all especially in the hall but how do I disprove a smell
